Abstract

Compact disk changer with a playback section and a magazine with compartments for holding compact disks. The playback section and the magazine are moved relative to each other up and down for removing compact disks from the magazine. The compact disks are scanned optically in the magazine compartment to attain a predetermined relative position between the playback section and the magazine for the purpose of removing a selected disk. The compact disks in the compartments are detected by light conductors which extend into the magazine compartments. The disks have peripheral rims that do not reflect light.
