Information recording disk playback apparatus










Image Number 10 for United States Patent #5105414.

An information recording disc playback apparatus has an optical pickup for reading recorded information from a disc clamped on a turntable by a disc clamp mechanism while the disc is being rotated. The disc clamp mechanism comprises a presser member for pressing the disc against the turntable under magnetic forces, and a movable member supporting the presser member idly and movable by a drive mechanism for displacing the presser member toward and away from the turntable. After the disc has been pressed against the turntable by the presser member, the movable member is movable within a gap defined between itself and the presser member. By the movement of the movable member within the gap, the height of an optical pickup mounted on the movable member can be adjusted with respect to the recording surface of the disc.
