For example, the operation unit 5 outputs to the controller 8 a program start signal that instructs the start of the program setting process for creating the dubbing target list, a high-speed dubbing signal that instructs the start of the high-speed dubbing process, and the like.
[0028]
The display unit 6 displays predetermined marks, character strings, and the like, and shows the operating status of the recording / reproducing apparatus to the user.
The timer 7 measures time according to the control of the controller 8. The timer 7 outputs a progress signal indicating that the predetermined time has elapsed to the controller 8 every predetermined time (for example, 1 minute). Thereby, the dubbing prohibition time set for each piece of music data is counted, and the remaining time of the dubbing prohibition time recorded in the music management table is updated.
[0029]
The controller 8 is composed of a microcomputer composed of a CPU (Central Processing Unit) and a peripheral LSI (Large Scale Integration). The controller 8 creates the dubbing target list, performs high-speed dubbing of music data, and creates the music management table. Further, the controller 8 updates the remaining time of the dubbing prohibition time recorded in the music management table in response to the elapsed signal supplied from the timer 7. Then, the controller 8 completely deletes the information related to the music data whose remaining time is zero from the music management table by overwriting predetermined data, for example. By this deletion, the dubbing order of each piece of music data recorded in the music management table is automatically advanced one by one. Detailed operation of the controller 8 will be described later.
[0030]
Next, the operation of the recording / reproducing apparatus configured as described above will be described.
(1) When setting music data for high-speed dubbing
First, a user of the recording / reproducing apparatus sets a predetermined number of CDs on which music data to be set for high-speed dubbing is set in the CD reproducing unit 1 and the MD as a dubbing destination in the MD recording / reproducing unit 2. set.
[0031]
The CD playback unit 1 obtains the CD total playback time, the number of tracks, the individual playback time, and the like from the TOC information of each set CD, generates the CD track information, and outputs it to the controller 8.
The MD recording / reproducing unit 2 acquires the number of MD tracks from the set MD TOC information, generates the MD track information, and outputs the MD track information to the controller 8.
[0032]
The controller 8 stores the CD track information supplied from the CD playback unit 1 and the MD track information supplied from the MD recording / playback unit 2 in the memory 4.
Next, the user of the recording / reproducing apparatus presses a predetermined operation button provided in the operation unit 5 in order to set music data to be dubbed at high speed. As a result, the operation unit 5 outputs a program start signal for instructing the start of the program setting process to the controller 8.
[0033]
In response to the program start signal from the operation unit 5, the controller 8 starts the program setting process shown in FIG.
First, the controller 8 clears the total program time stored in the memory 4. Specifically, the controller 8 sets the total program time in the memory 4 to zero (step S101).
[0034]
The user of the recording / reproducing apparatus operates the operation unit 5 in a predetermined procedure, and selects one piece of music data to be set according to the order of setting. Specifically, the user operates the operation unit 5 according to a predetermined procedure, and the disc number of the CD in which the music data to be set is recorded and what number the music data to be set is recorded. Select the track number indicating. As a result, the operation unit 5 outputs the disc number and track number of the CD selected by the user to the controller 8.
[0035]
The controller 8 specifies music data to be set from the disk number and track number from the operation unit 5 and the CD track information in the memory 4, and information indicating the specified music data is recorded in the music management table in the memory 4. It is determined whether or not it has been performed (step S102). Thereby, the controller 8 determines whether or not the music data to be set is a high-speed dubbing prohibition target.
[0036]
When it is determined that the data is not recorded (step S102; NO), the controller 8 performs a process of step S106 described later.
On the other hand, if it is determined that it is recorded (step S102; YES), the controller 8 determines whether or not the music data to be set is subject to high-speed dubbing prohibition even when the high-speed dubbing starts (step S103). Specifically, the controller 8 determines whether or not the music data to be set is a high-speed dubbing prohibition target at the start of the high-speed dubbing from the total program time recorded in the memory 4 in step S106 described later.
[0037]
For example, when two music data are already set as high-speed dubbing targets, the sum of the individual reproduction times of the two music data is recorded in the memory 4 as the total program time. The controller 8 obtains the total program time from the memory 4 and obtains a dubbing time required for high-speed dubbing of two music data already set as high-speed dubbing targets. Specifically, the controller 8 calculates dubbing time by calculating, for example, (total program time) / (speed magnification of high-speed dubbing). Further, the controller 8 acquires the remaining time of the dubbing prohibition time set for the music data to be set from the music management table. Then, the controller 8 determines whether or not the acquired remaining time is shorter than the dubbing time.
[0038]
The dubbing time is shorter than the time until high-speed dubbing of music data to be set is actually started. Therefore, if the remaining time of the dubbing prohibition time is shorter than the dubbing time, it is possible to determine that the music data to be set is excluded from the high speed dubbing prohibition target at the start of the high speed dubbing.
[0039]
When it is determined that the remaining time is longer than the dubbing time, that is, when it is determined that high-speed dubbing is prohibited at the start of high-speed dubbing (step S103; YES), the controller 8 controls the display unit 6 to set Is displayed as a warning message indicating that there is a possibility that high-speed dubbing may not be performed (step S104). Thereby, the controller 8 confirms with the user of the recording / reproducing apparatus whether or not the music data to be set is set as the music data to be dubbed at high speed. The controller 8 may display the remaining time of the high-speed dubbing prohibition time set in the music data to be set together with the warning message.
[0040]
When the music data to be set is not set as the music data to be dubbed, the user of the recording / playback apparatus operates the operation unit 5 to cancel the setting. As a result, the operation unit 5 outputs a cancel signal instructing cancellation of the setting to the controller 8.
[0041]
The controller 8 determines whether or not the cancel signal is supplied from the operation unit 5 within a predetermined time (step S105).
When it is determined that the cancel signal is not supplied (step S105; NO), the controller 8 determines that the setting target music data is set as the dubbing target music data, and performs the process of step S106 described later.
On the other hand, when it is determined that the cancel signal is supplied (step S105; YES), the controller 8 performs a process of step S107 described later.
[0042]
When it is determined in the process of step S103 that the remaining time is shorter than the dubbing time, that is, when it is determined that the high-speed dubbing is not prohibited at the start of high-speed dubbing (step S103; NO), the controller 8 sets the music to be set. Set the data as music data to be dubbed. Specifically, the controller 8 records information indicating the music data that is newly dubbing target in the dubbing target list of the memory 4. Further, the controller 8 obtains the individual reproduction time of the music data newly targeted for dubbing from the CD track information in the memory 4 and adds it to the total program time (step S106).
[0043]
Thereafter, the controller 8 determines whether a program end signal instructing the end of the program setting process is supplied from the operation unit 5 or whether a disc number and a track number indicating the music data to be set next are supplied. (Step S107). If it is determined that the disc number and the track number have been supplied (step S107; number), the controller 8 returns to step S102.
On the other hand, when it is determined that the program end signal is supplied (step S107; end), the controller 8 ends the program setting process.
[0044]
As described above, the music data to be subjected to high-speed dubbing and the dubbing order are programmed. That is, a dubbing target list indicating the music data that is the target of high-speed dubbing and the dubbing order is created. Further, as described above, if there is a possibility that the music data to be set is subject to high-speed dubbing prohibition even when high-speed dubbing is started, the user of the recording / reproducing apparatus is notified of the possibility that high-speed dubbing will not be performed. Thus, the user of the recording / reproducing apparatus can know the existence of music data that may not be dubbed at high speed before actually starting high speed diving.
[0045]
(2) When dubbing programmed music data at high speed
After the program setting process is completed, the user of the recording / reproducing apparatus presses a predetermined operation button provided on the operation unit 5 in order to perform high-speed dubbing of music data. As a result, the operation unit 5 outputs to the controller 8 a high-speed dubbing signal that instructs the start of the high-speed dubbing process.
[0046]
In response to the high-speed dubbing signal supplied from the operation unit 5, the controller 8 starts the high-speed dubbing process shown in FIG.
First, the controller 8 acquires a dubbing target list stored in the memory 4 (step S201).
[0047]
Then, the controller 8 determines whether or not one of the music data recorded in the dubbing target list, for example, the music data having the first dubbing order is recorded in the music management table of the memory 4 ( Step S202). Thereby, the controller 8 determines whether or not the music data to be dubbed is a high-speed dubbing prohibition target.
When it is determined that the data is recorded (step S202; YES), the controller 8 performs a process of step S204 described later.
[0048]
On the other hand, if it is determined that it is not recorded (step S202; NO), the controller 8 controls the CD playback unit 1 and the MD recording / playback unit 2 to quickly transfer the music data determined as not recorded from CD to MD. Dubbing is performed (step S203). At this time, the controller 8 records information (total playback time, number of tracks, and track number) indicating the music data to be dubbed at high speed in the music management table of the memory 4. Further, the controller 8 sets the dubbing prohibition time for the music data to be dubbed at high speed by recording the dubbing prohibition time (for example, 74 minutes) in the remaining time of the music management table. If the timer 7 is not operating at the start of high-speed dubbing, the controller 8 operates the timer 7 to count the time.
[0049]
Thereafter, the controller 8 refers to the dubbing target list in the memory 4 and determines whether or not there is music data that is the next dubbing target (step S204).
If it is determined that it exists (step S204; YES), the controller 8 returns to step S202, and performs the above-described process for the music data with the next dubbing order.
On the other hand, when determining that it does not exist (step S204; NO), the controller 8 ends the high-speed dubbing process.
[0050]
As described above, predetermined music data is sequentially dubbed from CD to MD at high speed. Further, when setting music data to be dubbed at a high speed, the user of the recording / reproducing apparatus is notified of the music data that may be subject to high-speed dubbing prohibition at the start of high-speed dubbing by a warning message or the like. Thereby, the user of the recording / reproducing apparatus can know in advance the existence of music data that cannot be dubbed at high speed, and can take measures such as delaying the start of high-speed dubbing. Therefore, there is no need to redo the setting of music data to be dubbed at high speed, and predetermined music data can be dubbed efficiently at high speed.
[0051]
(Concrete example)
Next, the operation of the recording / reproducing apparatus will be described using a specific example.
1. Example 1
First, a case where the user of the recording / playback apparatus sets music data to be dubbed at high speed and the order thereof will be described. It is assumed that the high speed dubbing is performed at a speed twice the normal speed.
[0052]
The user of the recording / reproducing apparatus sets to perform high-speed dubbing on three pieces of music data recorded on different CDs. Specifically, the music data recorded first on the track 1 of the disk 2 is recorded first, the music data recorded on the track 3 of the disk 1 second, and the music data recorded on the track 1 of the disk 3 third. Set to perform high-speed dubbing of music data. It is assumed that information indicating the second music data is recorded in the music management table of the memory 4.
[0053]
A user of the recording / reproducing apparatus sets three CDs on which music data to be set is recorded in the CD reproducing unit 1 and sets an MD as a dubbing destination in the MD recording / reproducing unit 2. It is assumed that no music data is recorded on the dubbing destination MD.
[0054]
The CD playback unit 1 obtains the CD total playback time, the number of tracks, the individual playback time, etc. from the TOC information of each set CD, and generates, for example, the CD track information shown in FIG. Output to the controller 8.
The MD recording / reproducing unit 2 acquires the number of MD tracks from the set MD TOC information, generates, for example, the MD track information shown in FIG.
[0055]

First, the controller 8 clears the total program time stored in the memory 4 (step S101).
[0057]
The user of the recording / reproducing apparatus operates the operation unit 5 according to a predetermined procedure. First, the disc number (disc 2) and track number (track 1) of the CD on which the music data to be set first is recorded. ) Is selected. The operation unit 5 outputs the disc number (disc 2) and track number (track 1) of the CD selected by the user to the controller 8.
[0058]
The controller 8 identifies the music data to be set from the CD disk number and track number of the CD from the operation unit 5 and the CD track information in the memory 4, and information indicating the identified music data is the music management table in the memory 4. Is recorded (step S102). The memory 4 stores a song management table shown in FIG.
In this case, the controller 8 determines that the information indicating the music data recorded on the track 1 of the disk 2 is not recorded in the music management table (step S102; NO).
[0059]
Then, the controller 8 sets the music data recorded on the track 1 of the disc 2 as music data to be dubbed. Specifically, as shown in FIG. 6B, the controller 8 sets the music data recorded on the track 1 of the disk 2 as the music data having the first dubbing order, and indicates the music data. Is recorded in the dubbing target list in the memory 4. Further, the controller 8 acquires the individual reproduction time (12 minutes) of the music data recorded on the track 1 of the disk 2 from the CD track information in the memory 4 and adds it to the total program time (step S106).
[0060]
Thereafter, the controller 8 determines whether a program end signal instructing the end of the program setting process is supplied from the operation unit 5 or whether a disc number and a track number indicating the music data to be set next are supplied. (Step S107).
[0061]
In this case, the user of the recording / reproducing apparatus operates the operation unit 5 to select the disc number (disc 1) and track number (track 3) of the CD on which the music data that is the second setting target is recorded. . The operation unit 5 outputs the disc number (disc 1) and track number (track 3) of the CD selected by the user to the controller 8.
[0062]
The controller 8 determines that the disk number and track number have been supplied (step S107; number), and returns to step S102 to perform the above processing. However, information indicating the music data recorded on the track 3 of the disc 1 is recorded in the music management table as shown in FIG. Therefore, the controller 8 determines in the process of step S102 that information indicating the music data recorded on the track 3 of the disk 1 is recorded in the music management table of the memory 4 (step S102; YES).
[0063]
Subsequently, the controller 8 determines whether or not the music data recorded on the track 3 of the disc 1 is a high-speed dubbing prohibition target even when the high-speed dubbing is started (step S103). Specifically, the controller 8 obtains the total program time from the memory 4 and obtains the dubbing time. In this case, since the total program time is 12 minutes, the dubbing time is 12/2 = 6 minutes. Further, the controller 8 acquires the remaining time of the dubbing prohibition time set for the music data recorded on the track 3 of the disc 1 from the music management table. As shown in FIG. 6A, the remaining time is 74 minutes. Then, the controller 8 determines whether or not the acquired remaining time is shorter than the dubbing time.
[0064]
In this case, the controller 8 determines that the remaining time is longer than the dubbing time, that is, the high-speed dubbing prohibition target even when high-speed dubbing is started (step S103; YES). Then, the controller 8 controls the display unit 6 to display a warning message that the music data to be set is subject to high-speed dubbing prohibition and may not be high-speed dubbed (step S104). Thereby, the controller 8 confirms with the user of the recording / reproducing apparatus whether or not the music data to be set is set as the music data to be dubbed at high speed. The controller 8 may display the remaining time (74 minutes) of the high-speed dubbing prohibition time set in the music data to be set together with the warning message.
[0065]
Thereafter, the controller 8 determines whether or not a cancel signal for instructing cancellation of the setting is supplied from the operation unit 5 within a predetermined time (step S105).
If the controller 8 determines that the cancel signal is not supplied within a predetermined time (step S105; NO), the controller 8 determines that the music data recorded on the track 3 of the disc 1 is set as the music data to be dubbed.
[0066]
Then, as shown in FIG. 6B, the controller 8 sets the music data recorded on the track 3 of the disk 1 as the music data having the second dubbing order, and stores information indicating the music data in the memory 4. To the dubbing target list. Further, the controller 8 acquires the individual reproduction time (10 minutes) of the music data recorded on the track 3 of the disk 1 from the CD track information of the memory 4 and adds it to the total program time (step S106).
[0067]
Thereafter, the controller 8 determines whether a program end signal indicating the end of the program setting process is supplied from the operation unit 5 or whether a disc number and a track number indicating the music data to be set next are supplied ( Step S107).
In this case, the user of the recording / reproducing apparatus operates the operation unit 5 to select the disc number (disc 3) and track number (track 1) of the CD on which the music data that is the third setting target is recorded. . The operation unit 5 outputs the disc number (disc 3) and track number (track 1) of the CD selected by the user to the controller 8.
[0068]
The controller 8 determines that the disk number and track number have been supplied (step S107; number), and returns to step S102 to perform the above processing. However, the information indicating the music data recorded on the track 1 of the disk 3 is not recorded in the music management table as shown in FIG. Therefore, the controller 8 determines in the process of step S102 that information indicating the music data recorded on the track 1 of the disk 3 is not recorded in the music management table of the memory 4 (step S102; NO).
[0069]
Then, in the same manner as described above, the controller 8 sets the music data recorded on the track 1 of the disk 3 as the third music data in the dubbing order as shown in FIG. Is recorded in the dubbing target list in the memory 4. Further, the controller 8 acquires the individual reproduction time (8 minutes) of the music data recorded on the track 1 of the disk 3 from the CD track information in the memory 4 and adds it to the total program time (step S106).
[0070]
Thereafter, the controller 8 determines whether a program end signal indicating the end of the program setting process is supplied from the operation unit 5 or whether a disc number and a track number indicating the music data to be set next are supplied ( Step S107).
[0071]
In this case, since there are three pieces of music data to be set, the user of the recording / playback apparatus presses a predetermined operation button provided in the operation unit 5 in order to end the program setting process. As a result, the operation unit 5 outputs a program end signal to the controller 8.
As a result, the controller 8 determines that the program end signal has been supplied (step S107; end), and ends the program setting process.
[0072]
As described above, the music data that is the object of high-speed dubbing and the dubbing order thereof are set, and the music data that is the object of high-speed dubbing and the dubbing target list indicating the dubbing order are created. In addition, as described above, if there is a possibility that high-speed dubbing is prohibited at the start of high-speed dubbing, the recording / playback apparatus user is notified that high-speed dubbing may not be possible. The Thereby, the user of the recording / reproducing apparatus can know the existence of music data that may not be dubbed at high speed before actually starting high-speed dubbing.
[0073]
2. Example 2
Next, the case where the three music data set in the specific example 1 are dubbed at high speed will be described. It is assumed that the music data having the second dubbing order is a target for which high speed dubbing is prohibited even when the high speed dubbing is started.
The user of the recording / reproducing apparatus presses a predetermined operation button provided on the operation unit 5 in order to perform high-speed dubbing of music data after the program setting process is completed. As a result, the operation unit 5 outputs a high-speed dubbing signal to the controller 8.
[0074]
In response to the high-speed dubbing signal supplied from the operation unit 5, the controller 8 starts the high-speed dubbing process shown in FIG.
First, the controller 8 acquires the dubbing target list shown in FIG. 6B from the memory 4 (step S201).
[0075]
Then, the controller 8 determines whether or not the information indicating the music data with the first dubbing order shown in the dubbing target list is recorded in the music management table of the memory 4 (step S202).
[0076]
In this case, as shown in FIGS. 6A and 6B, the music data with the first dubbing order indicated in the dubbing target list is not recorded in the music management table. For this reason, the controller 8 determines that it is not recorded (step S202; NO), controls the CD playback unit 1 and the MD recording / playback unit 2, and selects the music data with the first dubbing order shown in the dubbing target list. High-speed dubbing from CD to MD is performed (step S203).
[0077]
At this time, the controller 8 records information (total playback time, number of tracks, and track number) indicating the music data to be dubbed at high speed in the music management table as shown in FIG. Further, the controller 8 sets the dubbing prohibition time for the music data to be dubbed at high speed by recording the dubbing prohibition time (for example, 74 minutes) in the remaining time of the music management table. If the timer 7 is not operating at the start of high-speed dubbing, the controller 8 operates the timer 7 to count the time.
[0078]
Thereafter, the controller 8 refers to the dubbing target list in the memory 4 and determines whether or not there is music data that is the next dubbing target (step S204).
In this case, the controller 8 determines that it exists (step S204; YES), returns to step S202, and information indicating the music data with the second dubbing order in the dubbing target list of FIG. It is determined whether or not it is recorded in the song management table.
[0079]
In this case, as shown in FIGS. 6 (a) and 6 (b), the music data with the second dubbing order shown in the dubbing target list is recorded in the music management table. For this reason, the controller 8 determines that it is recorded (step S202; YES), and determines whether or not music data that is the next dubbing target exists in the dubbing target list in the memory 4 (step S204). .
[0080]
In this case, the controller 8 determines that it exists (step S204; YES), returns to step S202, and performs the above processing on the music data whose dubbing order is third in the dubbing target list of FIG. 6B.
[0081]
The information indicating the music data with the third dubbing order shown in the dubbing target list is not recorded in the music management table as shown in FIGS. 6 (a) and 6 (b). For this reason, the controller 8 controls the CD playback unit 1 and the MD recording / playback unit 2 to perform high-speed dubbing of the music data having the third dubbing order shown in the dubbing target list from CD to MD (step S203).
[0082]
At this time, the controller 8 records information (total playback time, number of tracks, and track number) indicating the music data to be dubbed at high speed in the music management table as shown in FIG. Further, the controller 8 sets the dubbing prohibition time for the music data to be dubbed at high speed by recording the dubbing prohibition time (for example, 74 minutes) in the remaining time of the music management table.
[0083]
Thereafter, the controller 8 refers to the dubbing target list in the memory 4 and determines whether or not there is music data that is the next dubbing target (step S204).
In this case, the controller 8 determines that it does not exist (step S204; NO), and ends the high-speed dubbing process.
[0084]
As described above, predetermined music data is sequentially dubbed from CD to MD at high speed. Also, music data that is a target of high-speed dubbing prohibition at the start of high-speed dubbing is not high-speed dubbed, so that the copyright of the music data can be protected. Further, when setting music data to be dubbed at high speed, the user of the recording / playback apparatus is notified of the music data that may be subject to high-speed dubbing prohibition at the start of high-speed dubbing by a message or the like. Thereby, the user of the recording / reproducing apparatus can know in advance the existence of music data that cannot be dubbed at high speed, and can take measures such as delaying the start of high-speed dubbing. Accordingly, there is no need to redo the setting of music data to be dubbed at high speed, and predetermined music data can be dubbed at high speed efficiently.
[0085]
If the controller 8 determines in step S103 of the program setting process that the music data to be set is a high-speed dubbing prohibition target even at the start of the high-speed dubbing, the controller 8 does not confirm the user with the high-speed dubbing data. It may not be set as a dubbing target. Specifically, the controller 8 may not perform the process of step S105 of the program setting process. Note that the warning message may be displayed only to notify the user that the music data to be set is a high-speed dubbing prohibition target.
[0086]
Further, the controller 8 may display the warning message or the like displayed in step S104 of the program setting process when it is determined that it is recorded in the song management table in the process of step S102.
[0087]
If the controller 8 determines that it is recorded in the song management table in step S102 of the program setting process, the controller 8 may perform the process of step S107 without setting the song data to be set as a high-speed dubbing target. . Specifically, the controller 8 may perform the process of step S107 without performing the processes of steps S103, S104, and 105 if it is determined in step S102 that it is recorded in the song management table. However, if the controller 8 determines that it is recorded in the song management table in step S102, the controller 8 displays the above warning message and the like to notify the user that the song data to be set is a high-speed dubbing prohibition target. May be.
[0088]
Further, the method of presenting to the user that the music data to be set is subject to high-speed dubbing prohibition is not limited to the method of displaying the warning message. For example, the user may be notified by voice or a warning lamp that the music data to be set is subject to high-speed dubbing prohibition.
[0089]
Further, the information indicating the type of music data recorded on the reproduction track of the music management table may be anything as long as music data can be specified. For example, ISRC (International Standard Recording Code), which is information unique to the music indicated by the music data, may be used.
[0090]
The recording / reproducing apparatus can be applied not only to high-speed dubbing of music data from CD to MD, but also to high-speed dubbing of programs and data in general. For example, the present invention can also be applied to a case where image data or a program is dubbed at high speed onto a recording medium such as a CD-RAM or a DVD-RAM.
[0091]
The apparatus of the present invention does not need to use a dedicated apparatus, and can be realized by a normal computer. For example, a program and data for causing a computer to execute each of the processes described above are recorded on a recording medium (floppy disk, CD-ROM, etc.), distributed, installed, and executed on the OS. Can be realized.
Further, the program and data are not limited to the CD-ROM or the like, and may be distributed via a communication line or the like.
