2. Description of the Related Art In recent years, with the development of electronic technology, CDs (compact discs) and MDs for recording sound such as music have been developed.
2. Description of the Related Art Digital disks (called "disks") such as (minidisks) and disk reproducing devices (called "players") for reproducing sound from such disks are becoming widespread. In such a disc, a title is set for each disc and each track so that the user can easily identify a plurality of recorded contents (called tracks) recorded on each disc or one disc. Techniques for setting and displaying are also known.

[0003] Such a title is typically represented as text data representing a character string, and types of the title include a user title, a disc title, a track title and the like. Among them, the user title is freely set by the user of the disc reproducing apparatus for the disc or track, and is recorded in the memory of the disc reproducing apparatus in association with the disc ID number and the like, and cannot be rewritten. It can also be set for a disc such as a large CD.

A disc title and a track title are recorded on a recording medium itself in units of a disc and a track. For example, in an MD, at least one of these is set in commercially available music software. Disk playback devices that can set these to MDs recorded by the user have also become widespread. Also, C
Of the Ds, a conventional CD or disc playback device cannot handle either a disc title or a track title. However, if a disc compatible with a so-called CD-TEXT (called title media) and a disc playback device are combined, Can handle both titles and track titles.

[0005] As a disk reproducing apparatus capable of handling the above-mentioned titles, an in-vehicle disk reproducing apparatus, so-called car audio, is also known. It is not possible to display all of the above-mentioned titles at a time as information.

For this reason, in the conventional car audio system, a plurality of display modes can be manually selected, and the type of title to be displayed is uniquely fixed for each display mode. In such prior art, for example,
In the user title display mode, only the user title is displayed even if the display source disk unit is switched or the disc is switched. Similarly, in the disc title display mode, only the disc title is displayed, and the track title display mode is displayed. If so, only the track title was displayed.

[0007]

However, in the above-mentioned prior art, when a title of a type corresponding to a manually selected mode cannot be obtained, it is difficult to identify a disc or a track. there were. For example,
Since the user title is input by the user, there is little problem even if it is displayed uniformly, but it is not always input. Also, the MD disc title and the track title may or may not be input depending on the disc, regardless of the user's intention. Further, as for the CD, the title can be read and displayed only when both the disc and the car audio are compatible with the CD-TEXT as described above.

As described above, titles for each type such as disc titles and track titles may or may not exist, or may or may not be read, depending on conditions. For this reason, in the related art in which the display mode is manually selected, if a title that matches the display mode cannot be obtained, a character or mark indicating a blank or no title is displayed. In this case, the title display area cannot be effectively used, and it is difficult to identify the disc currently inserted in the car audio or its track.

The present invention has been proposed in order to solve the above-mentioned problems of the prior art.
