Abstract
A playback apparatus for use with disc media includes a disc clamping mechanism operable with the opening and closing of the disc holding device with respect to the body of the playback apparatus. Portions of the clamper are normally spring biased to an open or non-clamping state, and are moved by a cam to the clamping position when the holding device is closed.
