Abstract

A compact-disc digital audio player is described in which a user can store preferred selections on selected discs in a memory. The player can identify the disc from the subcode on the disc and can read the corresponding preferred selection out of the memory to play this preferred selection.

Claims

1. In an apparatus for reproducing information from a record carrier, said apparatus having read means for reading information from said record carrier and control means for controlling and read means in such a way that a selected part of the information read by the read means can be reproduced, said apparatus comprising:

storage means for storing respective identifications of a plurality of record carriers and preferred selections respectively corresponding to said record carriers;

identification means for determining the identification of a to be played record carrier;

means for detecting whether or not the determined identification of said to be played record carrier is stored in said storage means; and

means for setting said control means so that if said storage means, as detected by said detecting means, does contain an identification corresponding to the determined identification of said to be played record carrier, the preferred selection stored in said storage means corresponding to said to be played record carrier is automatically played.

2. An apparatus as claimed in claim 1 further comprising:

a control panel for enabling the user to make a selection to set said control means for controlling the reading of information from said to be played record carrier by said read means, said control panel including write means for optionally writing into said storage means a preferred selection of a record carrier and the determined identification found after the loading of said to be played record carrier, and selection means for making said preferred selection of said record carrier stored in said storage means.

3. An apparatus as claimed in claim 2, wherein the write means are further adapted to combine a code representing the identification and a code representing the preferred selection and write the combination as blocks into the storage means;

and wherein said blocks are read consecutively by a reading means for detecting whether the determined identification of a to be played record carrier corresponds to one of the respective identifications stored in the storage means.

4. An apparatus as claimed in claim 3, wherein said blocks further having added thereto by said write means a sequence number and a code which indicates the position of the next block;

and wherein the address of the next block is determined by said reading means as a function of the stored length of the block read.

5. An apparatus as claimed in claim 4, further comprising means for displaying the sequence number of the block which corresponds to a record carrier to be or being played.

6. Apparatus as claimed in claim 1, wherein said identification means receive a subcode supplied by a decoder circuit for identifying said to be played record carrier, the information on said record carrier being digital audio information encoded in accordance with a predetermined compact-disc digital audio standard.

7. An apparatus as claimed in claim 6, wherein the identification means can identify said to be played record carrier by selecting predetermined bit groups from a record-carrier index which is contained in said subcode.
