BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc reproducing apparatus for displaying a title of a disc.

[0002]

2. Description of the Related Art In a TOC area provided on a CD, the order of music, the start time, the end time, etc. are recorded for all music recorded on the CD. When playing a CD, when the pickup first reads the TOC area,
The system microcomputer reads an address from the subcode Q signal demodulated by the decoder unit and performs servo control and the like. At the time of searching, the entire pickup is moved by operating the carriage servo, and the target address is compared with the current address to reach the target address.

[0003] For this reason, an arbitrary track of a CD can be searched for in a short time, and various CDs can be reproduced by various reproducing functions.

As described above, the information in the TOC area of the CD includes, as described above, the order of music, the start time, the end time, etc. of all the music recorded on the CD, but the title of the disc itself. No information was given about.

For this reason, conventionally, as shown in FIG. 1, for example, a disc title of a CD reproduced by a single CD player 1 can be input in a control center 2.

In this case, disc title information is stored in a RAM 5 provided on the single CD player 1 side. The disc title information stored in the RAM 5 corresponds to the disc-specific identification data stored in the TOC area.
When a disc is loaded into the D player 1, disc title information is read from the RAM 5 and displayed on the display unit 6 of the control center 2. Reference numeral 3 indicates an amplifier, and reference numeral 4 indicates a speaker.

[0007]

By the way, in the above-mentioned conventional method for inputting disc title information, a single C
Since the capacity of the RAM 5 of the D player 1 is normally (2 k × 8 bits), information of up to 36 titles can be input.

[0008] However, CDs and CD-
When a multi-type CD player capable of reproducing a disc such as a ROM is incorporated in the system, the multi-type CD player does not include the RAM 5 provided in the single CD player 1, and thus the title information of the disc is stored. When storing, a RAM for a disc title memory on the control center 2 side is used.

However, the RA on the control center 2 side
M has a limit on the number of disc title information to be stored because of insufficient capacity.

When a multi-type CD player is incorporated in a system incorporating a single CD player, for example, it is possible to display title information inputted by each player, but it is possible to display title information inputted by each player. Since the playback of a single CD player and the playback of a multi-type CD player are performed in a crossed manner, it is necessary not only to input duplicate title information but also to reduce the number of CDs. There was a problem that the system could not be upgraded with the number of memory titles that followed.

[0011] The present invention has been made in view of such circumstances. By sharing title information from various players, it is possible to avoid duplication of title information for each player. It is an object to provide a playback device.

[0012]

According to the present invention, there is provided a disk reproducing apparatus for displaying title information given to a recording medium reproduced by one or more recording medium reproducing means in order to achieve the above object. The title of the recording medium

[0013]

In the disk reproducing apparatus of the present invention, when the connection detecting means detects the connection of the second recording medium reproducing means, the identification information transfer means operates the recording medium stored in the first recording medium reproducing means. Since the identification information is transferred to the second recording medium reproducing means side, when displaying the recording medium identification information, the recording medium identification information held in the second recording medium reproducing means side is taken out. Since it can be performed, sharing of title information from various players can be achieved.
