Abstract

In CD-players with a memory having A storage positions for the storage of titles recorded on a CD-record it can happen, that more titles C are on the CD-record than storage positions A provided therefore in the CD-record. In order to use the storage space better in these cases and to keep the access times to the single titles low, the difference of the start times of each two consecutive titles are stored, instead of storing the start times of the individual titles. The more titles that are recorded on a inserted CD-record, the better the storage space is used, and the more the access times are reduced.
