Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information recording apparatus with a continuation function of discontinuously recorded data and a continuation method of discontinuously recorded data.
[0002]
[Prior art]
Recording units such as one song are recorded in a plurality of audio data areas for recording audio information and one or a plurality of control data areas arranged therebetween, and link destination data for these audio data areas is recorded. Thus, there is an information recording / reproducing apparatus capable of performing predetermined recording / reproducing.
[0003]
An example of this will be described by taking as an example the case where audio data such as music is recorded using an MD (mini disk) and the recorded MD is reproduced. When audio data such as music is recorded on the MD by the magneto-optical modulation method, if recording from a blank disc, the data is recorded continuously from the innermost side to the outermost side of the signal track, and chain data accompanying the recording When an MD recorded in this way is reproduced, the optical pickup for optical signal reading is track jumped from the inner circumference side to the outer circumference side of the signal track or from the outer circumference side to the inner circumference side. Reading is continuously performed without any problem.
[0004]
However, if a part of the recorded track of the recorded MD is divided, erased, combined or otherwise edited, the continuous recording state from the inner periphery to the outer periphery is cut off, and a blank part is generated in the middle or skipped. By connecting the recorded tracks, audio data of a predetermined unit, for example, one song is reproduced.
[0005]
In the specific example of the audio data formed by joining the jumping data in this way, the format of the control data recorded in the UTOC information storage area located on the inner peripheral side of the MD is as shown by the symbol a in FIG. Are divided into a total of 574 storage areas from address number 0 to address number 573, track number 255 is recorded from address number 0 to 63, and two address numbers from address number 64 to address number 573 are recorded. Multiple sets of one set of data are recorded. For example, in one set of data consisting of address number 64 and address number 65, the start address and track mode are recorded in the address number 64 area, and the end address and its address are recorded in the address number 65 area. The link destination is recorded, and similarly, multiple sets of control data are recorded up to address number 573. That.
[0006]
In this detailed example, as shown by the symbol b in FIG. 8, the control data recording area is from 0 to 63 of the total data at addresses 0 to 573, and the audio data recording area is from addresses 63 to 573. It has become.
[0007]
When editing multiple songs, for example, when editing the first song to the first song by combining the first to third songs into the first song and the fourth song as the second song Is the first audio data composed of the start address 0000 to the end address 0015, the corresponding frame data composed of the address 0016 to the address 0028, and the start address 0029. Second audio data composed of end address 0057, frame data composed of address 0058 to address 0064 corresponding thereto, third audio data composed of start address 0065 to end address 0086, and The three are formed.
[0008]
The second music following the first music formed in this way is formed as the fourth audio data composed of addresses 0108 to 0206 via the blank data of addresses 0087 to 0107, and so on. Song data is formed. Since such data is not continuous, by performing a track jump from the inner circumference side to the outer circumference side of the MD signal track or from the outer circumference side to the inner circumference side, by performing discontinuous reading A predetermined song can be played.
[0009]
That is, as indicated by reference symbol c in FIG. 9, after the first piece of music is reproduced, the first audio data composed of the start address 0000 to the end address 0015 is reproduced, and then the start address of the second audio data. After jumping up to the track address (see symbol 1) and reproducing the audio data up to the end address 0057, track jumping up to the start address 0065 of the third audio data (see symbol 2) and reproducing the audio data up to the end address 0086 By doing so, the first music piece is reproduced.
[0010]
Therefore, the frame data composed of addresses 0016 to 0028 and the frame data composed of addresses 0058 to 0064 are jumped, and after the first music piece has been reproduced, the address 0087 After track jump (see reference numeral 3) in the blank portion of ˜0107, reproduction of the first song and the second song is completed by reproducing the audio data from the start address 0108 to the end address 0206 forming the second song. .
[0011]
Thereafter, after the signal is read by performing a track jump (see reference numeral 4) to the frame data composed of addresses 0016 to 0028 jumped as described above, the frame data composed of addresses 0058 to 0064. The track jump (see reference numeral 5) is performed to read the signal, and the data of a plurality of songs are reproduced in the same manner.
[0012]
When a new audio signal is recorded on the MD that has been recorded once, the signal is overwritten and recorded in the blank portion near the inner periphery of the recorded signal, and is recorded in the unrecorded portion when the blank portion disappears. In this way, chain information is written.
[0013]
[Problems to be solved by the invention]
Audio data recorded in the information recording device is recorded continuously from the innermost side of the signal track toward the outermost side if recording from a blank disc, and the chain data associated with the recording is continuous. When an MD recorded in this way is reproduced, it can be read continuously and efficiently without a track jump, but a part of the recorded track is divided, deleted, combined and edited. In this case, the continuous recording state from the inner periphery to the outer periphery is interrupted, and a blank portion is generated in the middle or tracks recorded in a jump are connected to reproduce a predetermined unit, for example, one piece of audio data. It will be.
[0014]
Therefore, when playing back, the optical pickup operation during reading (playback) to pick up jumping signals is based on chain information from the inner circumference to the outer circumference of the disc or from the outer circumference to the inner circumference. Since it is moved, a wasteful thread move operation is performed, and the search operation time at that time is wasted, and wasteful energy is used for reproduction. In this case, the battery operating time is shortened.
[0015]
Accordingly, an object of the present invention is to perform a useless operation or useless energy when reproducing a recorded medium even when a new signal is recorded or edited on a recording medium on which discontinuous recording is performed. It is an object to provide an information recording apparatus with a discontinuous recorded data continuation function and a continuation method of discontinuously recorded data without using any of them.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, a first embodiment will be described with reference to FIGS.
[0024]
In this embodiment, when new audio information is given, prior to recording the new audio information, when the discontinuously recorded data is reproduced, the reproduction data is stored in a memory, and a recorded audio data area And data continuation means configured to newly record each of the audio data and the control data based on the new audio information. Also, when the format of the control data recorded in the UTOC information storage area located on the inner periphery side of the MD is discontinuously recorded data similar to that shown in FIGS. 7 and 8 described in the section of the prior art The present invention is applied to.
[0025]
In addition, the first to third songs are combined into one song, the first song is edited, the fourth song is edited as the second song, and new voice information is recorded as the third song. . The data before recording is discontinuously recorded data as indicated by a symbol d shown in FIG. 1, and the first music data is composed of first audio data composed of a start address 0000 to an end address 0015, and It is composed of frame data composed of addresses 0016 to 0028 corresponding thereto, second audio data composed of start addresses 0029 to end addresses 0057, and addresses 0058 to addresses 0064 corresponding thereto. The frame data and the third audio data composed of the start address 0065 to the end address 0086 are formed.
[0026]
The second music following the first music formed in this way is formed as fourth audio data composed of addresses 0108 to 0206 via blank data of addresses 0087 to 0107. Since such data is not continuous, by performing a track jump from the inner circumference side to the outer circumference side of the MD signal track or from the outer circumference side to the inner circumference side, by performing discontinuous reading A predetermined song can be played.
[0027]
The operation in the case where the discontinuous recorded data is made continuous when new audio data is recorded will be described with reference to the flowcharts shown in FIGS. The first half of this flowchart is shown in FIG. 2, and is connected to the latter half shown in FIG. 3 via relay points (A) to (D) to constitute the whole.
[0028]
First, in step S1, it is determined whether or not the MD to be recorded is mounted at a predetermined position. If No, the process waits until it becomes Yes, or the relay point (D) is set as indicated by a broken line in FIG. Then, the process proceeds to FIG. 3 and ends. When the answer is Yes, the process proceeds to step S2, reading of the disc information is started, and reading of the UTOC information of the disc is started.
[0029]
Thereafter, the process proceeds to step S3 to determine whether or not the MD mounted on the device is a blank disk. If the answer is No, the process proceeds to the next step S4 and is there a recording instruction? If the recording instruction is not given (No), the process is terminated. If the recording instruction is given (Yes), the process proceeds to step S5 and the new recording signal is stored in the new recording temporary memory. Is stored, and is the link destination information all 00 in the next step S6? If all the link destination information is 00 (Yes), the final address at that time is stored in the UTOC address storage area A that is not 00, and the process proceeds to step S9. If NO in step S6 (No), the process proceeds to step S8, the address at the current time is stored in the non-00 UTOC address storage area A, and then the process proceeds to step S9.
[0030]
Step S9 determines whether or not the end address already stored in the address storage area A and the next start address are continuous. If they are continuous (in the case of Yes), they are continuous. The last address at that time is stored in the non-UTC address storage area B, and the process proceeds to step S11.
[0031]
In step S11, the address stored in step S7 or step S8 in the UTOC address storage area A is compared with the address stored in step S10 in the UTOC address storage area B, and the smaller address is stored in the memory C. Therefore, whether or not the address stored in step S11 is the final address is determined in the next step S12.
[0032]
In the case of No in step S12, the process proceeds to step S13, the track number corresponding to the address of the memory C is stored in the memory D, and the track after the track number corresponding to the address of the memory D is stored in the next step S14. The number is reproduced and stored in the temporary storage memory.
[0033]
Then, the process proceeds to the next step S15 to delete the data after the track number corresponding to the data stored in the previous step in the memory D, and the process proceeds to step S16 to record the information in the temporary storage memory in the MD, that is, Data is rewritten and the process proceeds to step S17. Note that a series of data rewrite executions from step S13 to step S16 is completed when step S12 is Yes, that is, when rewriting is performed up to the final address, the process proceeds to step S17.
[0034]
In step S17, data rewriting and new writing are performed by recording in the MD a new recording signal in the temporary signal recording memory that has already been rewritten in step S16.
[0035]
This is composed of the first audio data composed of the start address 0000 to the end address 0015 and the start address 0029 to the end address 0057 among the discontinuously recorded data as indicated by the symbol d in FIG. The second audio data to be processed and the third audio data composed of the start address 0065 to the end address 0086 are temporarily stored in the memory, and this data is continuously displayed as the first to third as indicated by the symbol e. The first music is recorded continuously with these three types of data.
[0036]
Next to the first music piece, the fourth audio data composed of the start address 0108 to the end address 0206 is temporarily stored in the memory, and this data is the second continuous with the data of the first music piece. Recorded as song data. Next, new audio data is recorded as the third music piece as indicated by the symbol f.
[0037]
Therefore, the final signal recording form is indicated by the symbol g, and as shown by the symbol h in FIG. 4, the first music data is formed from the start address 0000 to the end address 0066, and the second music data is the start address 0067. The third music piece data is formed from the start address 0167 to the end address 0235, and the frame data is formed from the start address 0236 to the end address 0255, so that the data is continuous.
[0038]
If it is determined in step S9 that the end address of the storage area B of the UTOC address and the next start address are not continuous (in the case of No), the process proceeds to step S18, and the non-continuous UTOC address. The final address at that time is stored in the storage area B, the process proceeds to step S11, and step execution is performed as described above.
[0039]
On the other hand, if Yes in step S3, that is, if the mounted MD is a blank disc, the process proceeds to step S19 and is there a recording instruction? When the recording instruction is not given (No), the process is terminated. When the recording instruction is given (Yes), the process proceeds to step S20, and the new recording signal is stored in the new recording temporary memory. After storing, the process jumps to step S17, and a new write is performed by recording the new recording signal in the temporary signal recording memory on the MD.
[0040]
The example described so far is an information recording apparatus that performs continuation of discontinuous recorded data in a voice-recorded MD when additionally recording new voice data. The present invention can also be applied to the case where discontinuous recording does not occur when performing. This example will be described as a second embodiment with reference to flowcharts shown in FIGS.
[0041]
In this embodiment, when discontinuous recorded data or continuous recorded data is edited, the reproduction data is stored in the memory, and the respective data in the recorded audio data area and the recorded control data area are edited. The data continuation means is configured to rewrite and record each of the audio data and the control data based on the data, and the operation thereof will be described with reference to the flowcharts shown in FIGS. The flowchart shows the first half portion in FIG. 5 and is connected to the latter half portion shown in FIG. 6 through relay points (E) to (G) to constitute the whole.
[0042]
First, in step S1, it is determined whether or not the MD to be recorded is mounted at a predetermined position. If the answer is No, the process waits until it becomes Yes, or the relay point (G) is set as indicated by a broken line in FIG. Then, the process proceeds to FIG. 6 and ends. When the answer is Yes, the process proceeds to step S2, reading of the disc information is started, and reading of the UTOC information of the disc is started.
[0043]
Thereafter, the process proceeds to step S3, where it is determined whether or not the MD mounted on the device is a blank disk. If it is a blank disk, the process ends. If not, the process proceeds to the next step S21. Is there an edit instruction? If no editing instruction is given (No), the process is terminated, and if an editing instruction is given (Yes), the process proceeds to step S22, where data already recorded is partially divided, An editing instruction such as partial combination or partial deletion is given, and the process proceeds to the next step S23.
[0044]
In step S23, is all link destination information 00? If all the link destination information is 00 (Yes), the process proceeds to step S24, the last address at that time is stored in the UTOC address storage area A that is not 00, and the process proceeds to step S26. If it is determined in step S23 that all the link destination information is not 00 (in the case of No), the process proceeds to step S25 to store the address at the current time in the UTOC address storage area A that is not 00, and then step S26. Proceed to
[0045]
In step S26, it is determined whether or not the end address already stored in the address storage area A and the next start address are continuous. If they are continuous (in the case of Yes), the process proceeds to step S27. Then, the last address at that time is stored in the non-continuous UTOC address storage area B, and the process proceeds to step S28.
[0046]
In step S28, the address stored in step S24 or step S25 in the UTOC address storage area A is compared with the address stored in step S27 in the UTOC address storage area B, and the smaller address is stored in the memory C. Therefore, it is determined in the next step S29 whether or not the address stored in this step S28 is the final address.
[0047]
In the case of No in step S29, the process proceeds to step S30, the track number corresponding to the address of the memory C is stored in the memory D, and the track after the track number corresponding to the address of the memory D is stored in the next step S31. The number is reproduced and stored in the temporary storage memory.
[0048]
Then, the process proceeds to the next step S32 to delete the data after the track number corresponding to the data stored in the previous step in the memory D, and the process proceeds to step S33 to record the information in the temporary storage memory in the MD. Rewrite data. Note that the series of data rewrite executions from step S30 to step S33 is completed when step S29 is Yes, that is, when rewriting is performed up to the final address, and the series of operations is terminated.
[0049]
If it is determined in step S26 that the end address of the storage area B of the UTOC address and the next start address are not continuous (in the case of No), the process proceeds to step S34, where the UTOC address is not continuous. The final address at that time is stored in the storage area B, the process proceeds to step S28, and step execution is performed as described above.
[0050]
On the other hand, in the case of Yes in step S3, that is, when the mounted MD is a blank disc, it is naturally terminated because editing cannot be performed.
[0051]
The two forms described so far are examples in which discontinuous recorded data is continuous during audio recording or discontinuous recorded data is continuous during editing. The data continuation means sometimes stores the reproduction data in a memory, and rewrites the recorded data of the audio data area and the recorded control data area as a recorded recording medium of continuous data. Of course, may be configured.
[0052]
In the above-described embodiment, the present invention is applied when the recorded medium on which data is recorded discontinuously is MD. However, the present invention can also be applied to media other than MD. .
[0053]
【The invention's effect】
As is apparent from the above description, the information recording device with the function of continuation of discontinuously recorded data and the method of continuation of discontinuously recorded data according to the present invention are data continuation means adopting a characteristic configuration or method. Alternatively, since the step is used, the audio data recorded in the information recording apparatus is continuously recorded from the innermost side of the signal track of the recording medium toward the outermost side, and the chain data accompanying the recording is continuous. Therefore, reading can be performed continuously and efficiently without a track jump during reproduction.
[0054]
Moreover, when editing such as dividing, erasing, combining, etc. is performed, the continuous recording state from the inner periphery to the outer periphery is cut off, a blank part is generated in the middle, or a predetermined unit is formed by joining tracks recorded in a jump. For example, even when one piece of audio data is reproduced, it is continued by the continuation means of the present invention, so that when the recording medium is reproduced, a skip signal is not picked up. Battery operation, especially in battery-powered equipment, without wasteful thread move operation without track jump from the inner circumference to the outer circumference or from the outer circumference to the inner circumference, without using wasted energy for playback The time can be lengthened.
[0055]
Therefore, the information recording apparatus with the function for continuation of discontinuously recorded data and the method for continuation of discontinuously recorded data according to the present invention records and edits a new signal on a recording medium on which discontinuous recording has been performed. Even if the recording is performed, it is possible to create a recorded medium that does not perform useless operation or use wasted energy when the recorded medium is reproduced.
