Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to a method for reproducing an optical disk player, and more particularly, to a method for reproducing an optical disk player by loading a magazine loaded with one or more optical disks into the player.

[Prior art]

FIG. 3 is a front view in which an optical disc represented by a plurality of compact discs (hereinafter abbreviated as discs) or the like as an example of a reproducing apparatus is stored in a magazine. Reference numeral 7 denotes a magazine in which these disks 1 to 6 are stacked and stored. FIG. 4 is a front view of a compact disk player (hereinafter abbreviated as a player) for operating the disks 1 to 6, and reference numeral 8 denotes a tray for loading the magazine 7,
Reference numerals 9 to 11 denote various operation switches and an indicator display unit. A plurality of disks 1 to 6 having the above-described configuration
The operation of the player loaded in the player will be described. First, as shown in the block diagram of FIG.
By operating a play key or a remote controller or the like (play key), a corresponding disc is selected (disc select). The disc is moved to the selected disc play position (disc set), a track number 00 portion is created only in the lead-in area, and the time item at this time is changed to determine a format for creating a disc table of contents. Table on content (hereinafter
Program information is read from the TOC (to be abbreviated as TOC), TOC read (information read), and operation keys (program memory), and reproduction is started based on the stored information (play). In the above TOC, the magazine 7 is mounted on the tray 8 and the power is turned off.
The state is stored during the state of N, 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, two sets of magazines each containing one or a plurality of discs
When A and B are to be played back in a predetermined order, first, magazine A is loaded on the tray 8, the play is ended according to the set desired program, and then the disc stored in the magazine B is played back. Since the storage of the program performed by the player with respect to the magazine A reproduced in the above is completely canceled, in order to mount the magazine A on the tray 8 again and play with the same program as the previous time, the program must be set again. It requires cumbersome operation. The present invention has been made in order to solve such a problem. When a plurality of sets of magazines each containing a disk are sequentially loaded and removed from a player, and each of the magazines is played back according to a predetermined program, the magazines are reproduced. It is an object of the present invention to provide a method of reproducing an optical disk player which does not need to set a program every time switching is performed.

[Means for Solving the Problems]

In order to achieve the above object, a method for reproducing an optical disk player according to the present invention is a method for reproducing an optical disk in a magazine capable of storing a plurality of optical disks according to a predetermined procedure. Information stored in a predetermined position of a predetermined optical disk among a plurality of optical disks, and program information indicating a reproduction order of information pieces stored in the plurality of optical disks in the magazine are stored in association with each other,
With the exchange of the magazine, every time the magazine is loaded on the optical disc player, the information stored in a predetermined position of the predetermined optical disc is read to determine the loaded magazine. Reproducing the plurality of optical discs based on the program information stored in correspondence with the information on the predetermined position.

[Operation]

The individual magazines in the present invention are identified at the time of reproduction by the TOC information and the like of the discs stored in the respective magazines, and are automatically reproduced according to the preset program information without having to set the program each time. I do.

【Example】

1 and 2 are block diagrams showing a method of reproducing an optical disc player according to an embodiment of the present invention. FIG. 1 is a block diagram showing a process in which individual magazines loaded on the player are stored by the player. FIG. 2 is a block diagram showing a process of identifying a loaded magazine based on the storage. In FIG. 1, first, a magazine 7 for accommodating at least one disk shown in FIGS. 3 and 4 of the conventional example is mounted on a tray 8, and then a play key is operated to select one disk. (Disc select), the selected disc is moved to the play position (disc set),
The TOC of the disc at this play position is read (TOC read). Next, a desired number of music pieces and a play order thereof are set from among a plurality of music pieces included in the disc (program setting). Store (program, TOC memory). For example, if there is a performance schedule of songs other than the discs included in the magazine, the second and third magazines storing the discs of these songs are loaded into the player in the same procedure as above, and the program and the program are loaded. Store TOC information in memory. When the above-described storage operation for each magazine is completed, as shown in FIG.
Alternatively, when an arbitrary magazine is loaded into the pre-ear (magazine set) and the first disc selected at the time of the above-mentioned storage operation is moved to the play position (first disc set), the player obtains TOC information of this disc. Read,
The program is compared with a plurality of TOC information stored in advance by the above operation (comparison with the TOC information in the memory), the loaded magazine is identified (magazine identification), and the program stored together with the TOC information is read out. Then, the program is read out (stored program), and the number of music pieces according to the schedule is played in a predetermined order (play). In the above-described embodiment, an example has been described in which the magazine is determined by the TOC of the first disk stored in the magazine loaded in the player and the program information is reproduced by the player. However, only the first information is necessarily stored. It does not need to be an operation, and TO of any disc in the same magazine
Even if the C or the TOC of a plurality of discs and the program information are stored, the magazine to be loaded at the time of play can be identified. Also, an example in which the TOC information and the program information are stored has been described. For example, six discs are stored in one set of magazines, and the number of songs in each of these discs is 8, 10, 5, 8, 8, 8 , 10, the sequence may be combined and stored together with the TOC information or the TOC information. Also, the total time of each disk may be stored instead of the number of music pieces. However, in this case, since the TOC reading operation of a plurality of disks is required, it is needless to say that the method of discriminating the magazine based on the TOC information on one disk is easier in operation. Further, in addition to the TOC and the number of music pieces described above, subcode information and program information in a disc that can specify a magazine by a memory stored in a player may be stored, and the magazine may be determined. The information stored in the memory of the player may include not only program information such as TOC information as discriminating material for magazines but also information such as magazine numbers for a plurality of magazines. In the above embodiment, the case of reproducing a disc has been described. However, the present invention may be applied to another optical disc such as a video disc.

【The invention's effect】

As is clear from the above description, the reproducing method of the optical disk player of the present invention stores TOC information or the like of an optical disk loaded in a magazine and predetermined program information for the optical disk in the player, and The magazine loaded in the player can be identified on the basis of the reading of, and the optical disc play can be performed according to a predetermined schedule without repeating the program setting operation.
