Abstract
A clamper mechanism in a changer-type disk playback device has a clamper and a clamper arm with a locking mechanism which engages the clamper. A magnet on the clamper attracts a corresponding magnet on a turntable of the disk playback device. This attraction disengages the locking mechanism thereby releasing the clamper and allowing the clamper to clamp a disk when the clamper arm is moved from a position in axial alignment with the turntable. The clamping mechanism moves in a plane substantially parallel to a recorded surface of stored disks in the playback device so that the space required to operate the clamping mechanism is minimized.
