As shown in the block diagram in the figure, first, use the play key in the operation switch 9 or the remote control to select the appropriate disc (disc select).
. This selected disc is moved to the play position (disc set), a track number is created in the area of Sudo-in, and a table of contents of the disc is created by changing the time item at this time. Table-on-content (1st below, T
OC), TOC read (information reading), program information is read (program memory) by operation keys, and playback is started based on these stored information (play). The TOC mentioned above is stored while the magazine 7 is attached to the tray 8 and the power is turned on, and the program information is also stored unless the clear key is operated. [Problems to be Solved by the Invention] In the conventional player as described above, for example, a 2m magazine A each stores one or more discs.
, B in the scheduled order, first load magazine A into tray 8, finish play according to the desired program you have set, and then play the disc stored in magazine B. The block performed by PlayX7 on the recycled magazine △

[] Since all of Gram's memories will be canceled, the magazine Δ will be used again.
In order to play the game using the same program as before by attaching the player to the tray 8, it is necessary to set the program again, which is a cumbersome operation. This invention was made to solve this problem, and when playing a plurality of magazines containing discs in a player according to a predetermined program while sequentially loading and unloading each magazine into a player, the magazine is An object of the present invention is to provide a playback method for an optical disc player that does not require program settings each time the program is switched. [Means for Solving the Problems] In the playback method of the optical disc player according to the present invention, a magazine containing at least one optical disc is loaded into the playback \7, and the TOC information of this optical disc and the like are stored in advance. By having the player store program information on the number of pieces to be performed and their performance order, and identifying the loaded magazine at the time of playback, the playback is automatically performed according to the NH program information.

[For production]

Each magazine in this invention is identified at the time of playback by the TOC information of the discs stored in each magazine, and is automatically played according to preset program information without having to set a program each time it is played. I do.

【Example】

1 and 2 are block diagrams showing a reproduction method of an optical disc player according to an embodiment of the present invention.
The figure is a block diagram showing a process in which each magazine loaded in the player is stored by the player, and FIG. 2 is a block diagram showing the process in which the loaded magazine is identified based on this storage. In FIG. 1, first, the magazine 7 that stores at least one disc of the conventional example shown in FIGS. 3 and 4 is mounted on the tray 8, and then one disc is selected by operating the play key. The selected disc is moved to the play position (disk set), and the TOC of the disc at this play position is read (TOC read). Next, set the desired number of songs from among the plurality of songs included in this disc and their performance order (program setting), and play the set program and the TOC information! ! The memory is stored in the RAM of the internal microcomputer (program, TOC memory). For example, if there is a performance schedule for discs other than the discs included in the magazine, a second disc containing the discs for these discs will be used. The third magazine is loaded into the player and the program and TOC information are stored in the memory using the same procedure as described above. After completing the storage operations for each magazine as described above,
As shown in the figure, the player is loaded with magazines according to a predetermined order, or any magazine starting with 1 (magazine set), and the first disc selected during the above memorization operation is moved to the play position. 1 disc set), the player reads the TOC information of this disc, compares it with the multiple TOC information stored in advance by the above operation, and compares it with the TOC information in memory), and compares it with the TOC information of the loaded magazine set. (magazine identification), sequentially outputs the programs stored together with the TOC information (reads the stored programs), and plays the number of songs according to the schedule in a predetermined order. In the above embodiment, an example was explained in which the magazine is determined based on the TOC of the first disc stored in the magazine worn by the player, and the program information is played back to the player. It is not necessary to store T of any disk in the same magazine.
Even if the TOC and program information of the OCl or 100 discs are stored, it is possible to identify the magazine to be loaded during play. In addition, an example was shown in which TOC information and program information are stored, but for example, six discs are stored in one set of magazines, and the number of tracks on each of these discs is 8, 10, 5, 8, 8. If it is a relatively random number sequence such as ゜10, this number sequence can be combined to create the TOC mentioned above.
+7'X information or TOC information may be stored together. Further, the total time of each disc may be stored instead of the number of songs. However, in this case, it is necessary to remove the TOCvc of multiple disks, so it goes without saying that the method of determining the magazine based on the TOC information of one disk is simple and easy to operate.Furthermore, , the above TOC, not only the number sequence of songs,
The magazine may be determined by storing in-disk loop code information and program information that allow the magazine to be identified using a memory stored in the player. Further, the information stored in the player's memory is not limited to TOC information of magazine identification material and program information, but may also include information such as magazine number for a plurality of magazines. In the above embodiment, the case of a disc playback method has been described, but the present invention may be applied to other optical discs such as a video Δ disc. Effects of the Invention 1 As is clear from the above description, the playback method of the optical disc player of the present invention is based on the reproduction method of the optical disc player of the present invention. It is possible to store the information in the player, identify the magazine loaded in the player based on reading this information, and perform optical disc play according to a predetermined schedule without repeating program setting operations.
