FIG. 2 is a data file for storing the type of the inserted medium for each drive. FIG. 3 is a data file for designating the order of judging the type of media, FIG. 4 is a data file for designating the time to start the reproduction of the media, and FIG. FIG. 6 is a data file for designating a drive number to be reproduced in continuous reproduction, and FIG. 7 is a data file for designating a title number to be reproduced in continuous reproduction. .

First, the operation when a medium is inserted will be described with reference to FIGS. When a medium is inserted into the drive, an interrupt occurs, and a program for determining the type of the inserted medium shown in the flowchart of FIG. 1 is started. First, in step 11, it is checked which drive the medium is inserted into, and then the medium inserted in the drive is replaced between step 13 and step 15 by the corresponding media type (music CD, photo CD,
Data is read according to a format corresponding to a video CD). If it is determined that the read data is data of a corresponding type of medium, the type of the medium is set at the corresponding drive number in the data file shown in FIG.

For a specific description, an example in which a video CD is inserted into the drive 2 will be described. When a video CD is inserted into the drive 2, an interrupt occurs as described above, and FIG.
A program for determining the type of media indicated by is started. Since the drive number where the medium is inserted is 2, the data is read from the drive 2 according to the format corresponding to the type of the specified medium in the order of steps 13 to 15. In step 13, data is read according to the format of the music CD. If it is determined that the read data is music CD data, a flag of the music CD is set to the number of the drive 2 shown in FIG. If it cannot be determined that the data is music CD data, the process proceeds to step 14. In step 14, data is read in accordance with the format of the photo CD. If it is determined that the read data is the data of the photo CD, the flag of the photo CD is set to the drive number 2 shown in FIG. If it cannot be determined that the data is the photo CD data, the process proceeds to step S15. In step 15, data is read according to the format of the video CD. If it is determined that the read data is the data of the video CD, the flag of the video CD is set to the number of the drive 2 shown in FIG. If it cannot be determined that the data is video CD data, the process proceeds to step S16. In step 16, since all media have already been checked, this CD-R
The OM determines that the medium cannot be played back and displays an error message on the screen or skips playback on the drive.

In the above description, the order of judging the type of each medium is as shown in FIG.
Although the order is D, video CD, this order is actually determined in the order shown in the data file of FIG. FIG.
Then, music CD in the area of 31 and photo C in the area of 32
The flag of the video CD is set in the areas D and 33. Therefore, the type of media is determined in the order of a music CD, a photo CD, and a video CD.

The user can arbitrarily edit the data file shown in FIG. 3 to change the order in which the types of media are determined. For example, if the frequency of using the video CD is the highest, the description of the video CD is described in the area 31 in FIG. By doing so, the media type of the video CD is determined first, so that the average time until the media is reproduced can be shortened.

When the power is turned on, it is determined whether or not the medium is inserted in all the drives. If the medium is inserted, all the procedures described in the example when the medium is inserted into the drive 2 are performed. Execute for the drive of, and initialize. Next, a method of designating reproduction will be described. In the present embodiment, reproduction can be designated using the following items as keys.

(A) Time designation * Automatic playback when media is inserted * Playback time designation by timer (B) Designation of media type * Designation to play only specific media (C) Drive number / song number, image Designation of title numbers such as display numbers * Continuous reproduction of only specified drive numbers * Continuous reproduction of only specified title numbers A method of specification for reproduction will be described with reference to FIGS. When it is desired to specify the reproduction time, a data file having the structure shown in FIG. 4 is used. To automatically start playback when a medium is inserted, the insertion automatic playback flag 41 is set to ON. To use the timer function, the reproduction timer flag 42 is set to ON, and time data is described in the data area 43 of the reproduction start time. In the example of FIG. 4, since “12:45:00” is described in the reproduction start time data area, 1
Playback starts automatically at 2:45:00.

To specify the type of media to be reproduced, the data file shown in FIG. 5 is used. It is possible to automatically determine, for each type of media, whether or not to play the media at the time of playback. The structure of the data file is as shown in FIG. Now, in the example of FIG.
Data area 51 is off, photo CD data area 52
Is on and the data area 53 of the video CD is off, so that even if a photo CD medium is inserted in the drive, it is skipped without being reproduced during continuous reproduction or the like.

For continuous reproduction, the data files shown in FIGS. 6 and 7 are used. In FIG. 6, 61, 62, and 6 are data areas for designating drive numbers to be reproduced.
3 is ON, OFF, and ON, respectively, so that only the drive 1 and the drive 3 are selected, and even if a medium is inserted into the drive 2, the medium is not reproduced. FIG.
7 is an area for specifying a title number to be reproduced in
1, 72, 73, 74, 75, 76, 77, 78, 79
Are on, on, off, off, off, off, on, off, and on, respectively. Therefore, the titles of the media to be reproduced are title 1 in drive 1, title N, title 1 in drive 2, and title in drive 3. Is the title N. However, as described above, since the drive 2 is not selected, the title in the drive 2 is not reproduced.

Although the embodiment has been described with respect to a disk reproducing apparatus having a plurality of drives, the same effect can be obtained with a disk reproducing apparatus having a single drive and a plurality of trays.
