Abstract
In CD-players with a memory (S) having A storage locations for the storing of the titles recorded on a CD-record, it can occur that the number of titles C recorded on the CD-record exceeds the number of storage locations A in the CD-player. In order to keep the access times for individual titles low, the memory (S) is partitioned into a first part (T1), having B storage positions, and a second part T2, having A-B storage positions. The titles 1 to B are stored in sequence in the B storage locations of the T1 portion of memory S. The remaining titles are distributed to the A-B storage locations of the part (T2) such that, no continuing sequence with the first B titles is formed. For example, the remaining C-B titles may be distributed evenly in the second part (T2) of memory S.
