DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc reproducing apparatus suitable for a CD player having a disc changer function.

[0002]

2. Description of the Related Art For example, in a CD player (disc player) having a disc changer function, unique information (TOC information) concerning each disc stored in a predetermined storage position in a magazine; Are searched, and the display, the content change, and the like can be performed.

[0003]

However, since the search for the unique information is performed for each disc when the CD player is set to the reproducing state, for example, when a plurality of disc changers are used in parallel, Display (confirmation) cannot be performed on the unique information of the disc changer that is not in the reproducing state, and it takes time to display the information.

[0004] It is an object of the present invention to provide a disc player in which display (confirmation), change, and the like of unique information can be quickly performed by performing search for unique information when the playback state is not in the reproduction state.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a disc player according to the present invention will be described below with reference to the drawings. In FIG. 1, a tape deck 3, tuners 5, 2
CD changers 7, 9 and display (TV monitor) 1
The system in which 1 is controlled is shown in a block diagram.

In each of the CD changers 7 and 9, a magazine in which, for example, ten CDs (compact discs) are stored in a predetermined storage position is set, and the CDs in the magazines are controlled by the head unit 1 including an operation unit. It is reproduced according to the operation situation.

When the CD changer 9 is playing back, that is, when the CD changer 7 is not playing back, the C stored in the magazine of the CD changer 7 is stored.
The TOC information related to D is searched.

In this case, as can be understood from FIG. 2, each of the predetermined storage positions A to J is searched.

[0014] The searches, subject to the CD changer 7 is detected that not playing (disc playback judgment means), first, CD is detected whether it is accommodated, C D is accommodated if not, the information indicating the fact (without DISC) is a RAM7A provided in CD changer 7 (memorize means), a predetermined storage position (e.g. B, H) to be stored in association.

On the other hand, when a CD is stored,
It is searched whether the TOC information (custom file) related to D is stored in the RAM 7B in the CD changer 7, and if it is stored, it is read (reproduced).
Stage), in correspondence with the predetermined storage position (e.g. A, J), R
Stored in AM7A.

If there is no TOC information, it is stored in the RAM 7A as "no custom file" (for example, predetermined storage positions C, D, and E).

For a CD for which a search has been completed, information indicating that the search has been completed is stored in the RAM 7A.
Information indicating a non-search is stored in the storage area of the RAM 7A for a CD for which a search has not been completed (for example, predetermined storage positions F and G).

The above search is performed on condition that the CD changer 7 is not being reproduced. Conversely, when the CD changer 7 is in the reproduction state and the CD changer 9 is stopped, the search is performed in the same manner as in the case of the CD changer 7. The TOC information and the like are stored in the RAM 9A of the CD changer 9, and the TOC information and the like are stored in the RAM 9B provided in the CD changer 9.

For example, when the tape deck 3 is being reproduced, the CD changers 7 and 9 are not being reproduced, so that each of them is searched.

The TOC information and the contents of the RAMs 7A and 9A are displayed on a display unit or the like provided in the head unit 1 so that the user can confirm the contents and change the contents (for example, The order of songs to be played can be changed). As described above, in this embodiment, the CD changer 7 or the CD changer 9
Is not being reproduced, the presence / absence of a CD, the presence / absence of TOC information, and its contents are searched.

Therefore, it is not necessary to search the CD changers 7 and 9 in the reproduction state as in the conventional case, so that TOC information and the like can be quickly displayed and changed, and the usability is excellent.

Therefore, for example, two disk players
Used and one disc player is playing
In the magazine set in the other disc player
Is searched for and stored.

As a result, the data is reproduced on the other disc player.
Display, change, etc. of retrieved / stored information
Since it can be performed quickly, usability is improved.

[0024]

As will be understood from the above description, the present invention
In the disc player according to
To the designated storage position, provided that the
It is detected whether or not the disc is stored (presence or absence).

When the disc is stored
Reads the unique information of the disc from the specified storage
Is done.

Also, information indicating that there is no disc, a unique
Indicates that the information and presence / absence of the disc has not been detected
Information is stored corresponding to the specified storage position of each disc
Is done.

As described above, the disc player performs the reproduction.
Not all standby disks are in standby state.
Of unique information related to and memory of the played unique information
To be stored in another device (Fig.
1 tape deck 3 etc.) during playback
The unique information of the disc can be reproduced.

Further, during this standby state, the disk in the magazine is
Discs are swapped or discs are stored in magazines
Even if the position is changed, the background
By reproducing the unique information of the disk,
There is an advantage that the information can be updated automatically.

Also, as described above, two disc players
During playback of one of the players,
Retrieve unique information about the stored disc and store it in memory
By storing it, for example,
When the playback of the disc on the
When moving to the playback of a disc in Reya, the other
Specific information on all discs stored in the disc player
Since the information has already been searched and stored, the display of this unique information,
There is an advantage that changes and the like can be made quickly.

Further, it is stored in the other disk player.
Of the disc in the disc-specific information
Display by reading and displaying the
While watching the title that was played,
Desired disc from among the multiple discs stored in the
There is also an advantage that it is possible to select and play back.
