ABSTRACT:
Audio/video disc playback apparatus includes a housing, a cover hinged to the housing, a rotor disc mounted in the housing and driven by a motor, and a pressure disc rotatably mounted underside of the cover for providing pressure contact with the rotor disc by the weight of the cover with an audio/video disc held therebetween. The pressure disc is loosely coupled to a mounting attached to the cover by means of a suspension which permits it to disengage from the mounting when the pressure disc comes to contact with the rotor disc as the cover is brought to the closed position so that the pressure disc is self-aligned to the axis of the rotor disc.
