The invention relates to a playback unit (1), specially a compact disc changer, which enables random selection of data groups stored on record carriers which are to be successively played back. The playback unit (1) comprises an input unit (5) and a random generator (10) for random selection of data groups stored in record carriers, specially compact discs, which can be loaded from a magazine (15) into the playback unit (1). The inventive playback unit makes it possible to predetermine the probability with which one of the data groups is selected by the random generator (10) to be played back after the playback device (1) has played back a data group stored in a record carrier which has been inserted in the drive (25) of the playback device (1), said data groups being stored in the same record carrier. |
