Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention stores recorded program information from a disc as an information recording medium used for recording program information, such as a compact disc on which digital audio signals are recorded. The present invention relates to a disc player that can be selected and played.

[0002]

2. Description of the Related Art A compact disc (hereinafter referred to as a CD) in which an audio signal is digitized and recorded as program information on a rotatable disc-shaped recording medium to form spiral recording tracks is used. A CD system in which a CD is loaded in a disc player to obtain reproduction program information, that is, a reproduction audio signal, has been proposed as an audio signal reproduction system capable of obtaining a high quality output audio signal.

In such a CD, usually, the innermost peripheral side of the spiral recording track is the reproduction start end and the outermost peripheral side is the reproduction end, and therefore, in the normal reproduction state, the center of the disc. Reproduction is performed from the part side to the outer peripheral part side. Then, the recorded program information is, for example, in the form of an aggregate of a plurality of segmented program information, each of which corresponds to each piece of music, and is usually regarded as accompanied by address data. There is. Further, in the innermost peripheral portion of the spiral recording track, the required time under the normal reproduction state from the reproduction start end to the beginning of each of the plurality of recorded division program information, the recorded division program information , The required time under the normal reproduction state from the reproduction start end to the end of the last one in the recording arrangement order of the recorded plurality of segmented program information, that is, data indicating the total reproduction time, etc. , "Index table data" (hereinafter referred to as TOC data).

Address data recorded along with a plurality of division program information is, for example, track number data indicating the recording arrangement order from the reproduction start end side of each division program information, and subdivision within one division program information. The index number data that represents the order of, and the relative time data that represents the playback time from the beginning of one division program information in minutes, seconds, and the number of frames with a cycle of 1 / 7.35 × 10 ³ , for example. In addition, the position on the spiral recording track includes the minutes and seconds of the reproduction time from the reproduction start end, and, for example, absolute time data that represents the number of frames with a cycle of 1 / 7.35 × 10 ^3. It is said that Since such address data is recorded along with each division program information, when reproducing the program information from the CD, the reproduction address data is used to reproduce from a desired portion of the program information. For example, it is possible to selectively reproduce the specific segment program information.

For this reason, the disc player used to obtain the reproduction program information from the CD has a normal reproduction operation mode in which a plurality of section program information recorded on the CD are sequentially reproduced from the reproduction start end portion in accordance with their recording arrangement order. Besides, for example, desired partition program information is selected from a plurality of partition program information recorded on a CD based on the track number data in the address data, and the reproduction order thereof is stored in the memory means in advance. The programmed reproduction operation mode in which the selected segmented program information is reproduced according to the reproduction order stored in the memory means, that is, the reproduction order programmed and set. And so on.

As described above, the disc player is supposed to be able to obtain the reproduction program information in the programmed reproduction operation mode for the mounted CD. For example, the reproduction of the program information from the CD is possible. When the CD is detached from the disc player due to the end of the sequence and then the CD is again loaded into the disc player and the program information is reproduced, a selection is made from a plurality of division program information. Even when it is desired that the selected desired segmented program information is reproduced in the same reproduction order as the previous one, the selection of the desired segmented program information and the reproduction order of the selected segmented program information are stored in advance in the memory means. The memorized programming has to be redone and is therefore a cumbersome operation. Will involve is it.

Therefore, with the intention of eliminating such inconvenience, for example, as shown in Japanese Patent Laid-Open No. 61-20282, the same CD is mounted even if it is repeatedly attached and detached. Each time, the programmed program which is stored in the memory means beforehand does not have to be reprogrammed with the desired playback order of the partitioned program information selected from the plurality of partitioned program information, and the programming once set is continuously effective. There have been proposals for dis-players that have been designed to be used.

In such a disc player, for example, when a CD is loaded and a programmed playback operation mode is set, desired segmented program information is selected from among the segmented program information recorded on the CD. hand,
The programming is performed such that their playback order is stored in the memory means and, for example, the T
The disc identification data obtained by using the OC data is stored in the memory means. Then, after the reproduction of the divided program information under the programmed reproduction operation mode is completed and the CD is detached, a new C
When D is mounted, the TOC data of the newly mounted CD is compared with the disc identification data previously stored in the memory means, and the TOC data of the newly mounted CD is stored in the memory means. If it is to check the disc identification data stored in the CD, the newly loaded CD is determined to have the same TOC data as the CD stored in the memory means. Is assumed to allow the programming previously performed to be executed as is.

[0009]

As described above, the disc identification data for the loaded CD is stored in the memory means so that the identity of the newly loaded CD can be determined. In the disc player, when the same CD is repeatedly attached and detached and the programmed reproduction operation mode is set, programming of the divided program information to be reproduced each time the CD is mounted should be performed. However, in such a case, programming that is automatically repeated for the same CD is performed by selecting each of the plurality of segment program information recorded in each CD as a selection unit. The newly installed CD is limited to the one that defines the playback order for the divided program information
It is hard to say that the advantage of discriminating the identity of is fully utilized.

In view of the above point, the present invention selects and reproduces each division program information or its portion from a disc in which TOC data is recorded in addition to address data and a plurality of division program information like a CD. In the case where the same disc is repeatedly used for information reproduction under the condition that the disc can be recorded, it corresponds to an arbitrarily selected address position in a plurality of division program information once set for the disc. A reproduction mode in which a portion is selected as a calling position and the program information is reproduced from each selected calling position,
An object of the present invention is to provide a disc player capable of obtaining a state which can be easily taken every time the disc is mounted.

[0011]

In order to achieve the above object, the disc player according to the present invention is selected for a disc on which TOC data is recorded in addition to address data and a plurality of division program information. Information reading means that can take different reading positions, a signal processing section that reproduces index table data, address data, and division program information based on a read signal from the information reading means, and a selected position on the disc. Address recorded in

When at least a part of the C data matches, the information reading means reads from the position on the disc corresponding to the reproduction specific address data stored in the memory means in association with at least a part of the reproduced TOC data. It is assumed to be in a ready state for performing the operation.

[0012]

In the disc player according to the present invention thus configured, when the disc is mounted and the position selecting means is operated under the call position selecting operation mode as a specific operation mode, the system control is performed. The unit specifies the address data recorded at the selected position on the disc according to the reading position on the disc of the information reading unit at that time, and subsequently, when the data storage instruction unit is operated, The reproduction specific address data, which is the reproduction output of the designated address data obtained from the signal processing unit, and at least a part of the reproduction TOC data obtained from the signal processing unit, are associated with each other,
Captured in memory means. Such playback specific address
The data is taken into the memory means, for example, a plurality of times, but at least a part of the reproduced TOC data obtained from the signal processing unit is taken into the memory means only once, and from the second time, Only the reproduction specific address data is captured in association with at least part of the previously captured reproduction TOC data. In this way
Based on the operation of the position selection means and the operation of the data storage instruction means, at least a part of the reproduction TOC data and the reproduction specific address data stored in the memory means are respectively
It is disc identification data that is considered to be unique to the disc and custom index data that represents an arbitrarily selected calling position on the disc.

Further, when a disc is newly mounted, the T newly obtained from the signal processor by the system controller.
When at least a part of the OC data and at least a part of the TOC data already stored in the memory means are compared with each other, and as a result, they are coincident with each other, the system control section causes the memory means to see the coincidence. The reproduction specific address data stored in the memory means in association with at least a part of the TOC data stored in the memory means is read out from the memory means, and, for example, a corresponding display is displayed on the display unit. Then, preparations are made for causing the information reading means to perform the reading operation from the calling position which is the position on the disk corresponding to the reproduction specific address data read from the memory means.

By doing so, when the same disc is repeatedly used for information reproduction,
After the identity is confirmed by the disc identification data consisting of at least a part of the reproduced TOC data, the read operation from the calling position on the disc determined based on the custom index data already obtained for the disc is facilitated. Will be able to start
Moreover, each of the calling positions is a portion corresponding to an arbitrarily selected address position in the plurality of section program information on the disc. Therefore, the advantage of discriminating the identity of the newly mounted disc can be fully utilized.

When the disc 1 is newly mounted under the custom index reproduction operation mode, the system control unit 10 newly discriminates the reproduction TOC data Toc from the decoder 7 to identify the disc identification data. Di is compared with the disc identification data Di already stored in the RAM 12, and when the two coincide with each other, the system control unit 10 discriminates the disc identification stored in the RAM 12 after the comparison. The custom index data Cx stored in the RAM 12 in association with the data Di is the RAM 1
2. Called from 2, each index "A" ~
“F” is displayed on the custom index display section 30,
The optical head 3 has a disk 1 corresponding to each of the custom index data Cx called from the RAM 12.
A readiness state for taking a reading operation from the calling position which is the upper position is taken.

Then, by operating the position selection switch 26a corresponding to any of the indexes "A" to "F" displayed on the custom index display section 30, the operated position selection by the optical head 3 is performed. Reading of the program information from the calling position on the disk 1 represented by the custom index data Cx with any of the indexes "A" to "F" corresponding to the switch 26a is started.

The system control unit 10 for controlling the reproduction of a plurality of pieces of segmented program information recorded on the disc 1 is configured by using, for example, a microcomputer. An example of the control operation program that is executed to control the information reproduction under the custom index reproduction operation mode will be described with reference to the flowchart shown in FIG.

In this program, after starting,
In the decision 42, it is determined whether or not the disc 1 is loaded in the disc player DP, and if it is not loaded, the determination in the decision 42 whether or not the disc 1 is loaded is repeated. Decision 42
If it is determined that the disc 1 is loaded in the disc player DP, the process proceeds to process 43, the disc identification data Di which is a part of the reproduced TOC data Toc is fetched into the internal memory, and the process proceeds to process 44. .

In the process 44, the RAM 12 is searched with the disc identification data Di fetched in the internal memory in the process 43, and the disc identification data Di and the RAM 12 fetched in the internal memory in the process 43 are searched.
The disc identification data Di that has been captured in the memory 12 is collated with the disc identification data Di that has been captured in the RAM 12 in the process 43 in the decision 45. Judge whether or not something exists. When the decision 45 determines that none of the disc identification data Di captured in the RAM 12 matches the disc identification data Di captured in the internal memory in the process 43, the process proceeds to a decision 48.
On the other hand, when it is determined that the disc identification data Di stored in the RAM 12 matches the disc identification data Di stored in the internal memory in the process 43, the process proceeds to process 46.

In process 46, decision 4
According to the determination in step 5, the RAM that is determined to match the disc identification data Di captured in the internal memory in process 43
The custom index data Cx captured in the RAM 12 in association with the disc identification data Di captured in the RAM 12 is read from the RAM 12 and captured in the internal memory.
Custom index data Cx read from 12
All or part of the indexes “A” to “F” accompanied by is displayed on the custom index display section 30, and the process proceeds to the decision 48.

In the decision 48, the operation for storing the new custom index data Cx in the RAM, which is performed by the operation of the position selection switch 26a and the filing switch 21, that is, the writing of the new custom index data Cx. If it is determined that an operation for writing new custom index data Cx has been performed, then in decision 49, the operation for that writing is performed at that time. Disc 1 installed
For the first write. Then, as a result of the determination in the decision 49, the operation for writing the new custom index data Cx determined to be performed in the decision 48 is
If it is for the first writing of the disc 1 mounted at that time, in process 50, the disc identification data Di captured in the internal memory in process 43 is stored in the RAM 12, and then, In the process 51, the new custom index data Cx already loaded in the internal memory is stored in the RAM 1
2 is stored in association with the disc identification data Di stored therein in the process 50. Then, after that, the process returns to the process 47, and in the process 50, the RAM 12
New custom index data C stored in
Any of the indexes "A" to "F" accompanied by x is displayed on the custom index display section 30, and the decision 48 is again made.

On the other hand, as a result of the judgment at the decision 49,
If the operation for writing the new custom index data Cx, which was determined to have occurred at decision 48, is not for the first write on the currently mounted disc 1, process 50.
In step 51, the new custom index data Cx already stored in the built-in memory is stored in the RAM 12 in association with the disc identification data Di already stored therein. Also in such a case, the process then returns to the process 47 and any one of the indexes “A” to “F” accompanied by the new custom index data Cx stored in the RAM 12 in the process 50 is displayed on the custom index display unit 30. Then, the decision 48 is again made.

Further, as a result of the judgment in the above-mentioned decision 48, if the operation for writing the new custom index data Cx is not performed, the disc 1 is detached from the disc player DP in the decision 52. It is determined whether or not the disc 1 has been ejected, and if the disc 1 has not been removed, the process returns to the decision 48. If it is determined by the decision 52 that the disc 1 has been detached from the disc player DP, the custom index data Cx stored in the internal memory is cleared in the process 53, and the custom index display section 30 displays. The display is erased and the process returns to the decision 42.

In the above example, the reproduction absolute time data included in the reproduction address data Q from the disc 1 is used as the custom index data Cx, but the disc 1 is used as the custom index data Cx. It is also possible to use the reproduction relative time data included in the reproduction address data Q from.
