Abstract
Apparatus for recording and/or playback of recordings on discs including a selective disc changer suited particularly for discs of the "compact disc" type. The playback unit has a housing mounted for helicoidal movement between a disc operating plane and an entrance plane for receiving a disc inserted edgewise and rolling into the housing along the entrance plane. A removable magazine provides a plurality of disc storage compartments arranged side by side and successively movable into alignment with the entrance plane, the magazine being received on a tray mounted on the chassis of the apparatus. The magazine is locked against being removed from the tray responsive to transfer of a disc from a storage compartment of the magazine to ensure that the magazine is locked against removal from the time that one of the discs stored in a compartment of the magazine has left its storage position until it is returned to the magazine compartment.
