ABSTRACT:
A disc-record player for recording and/or reading information on/from disc-shaped information carriers, in particular optical discs, of different diameter includes a frame, a turntable for the information carriers, and a device for moving said information carriers and bringing them into a well-defined position relative to the turntable. At least one positioning member is movable transversely of a loading direction; the positioning member is constructed, as a pivotal arm and includes a positioning element adapted to cooperate with the information carriers, and a detection unit for detecting the position of the information carriers. The detection unit includes a slide member movable in the loading direction of the information carriers and in an opposite direction, a guide element connected to the positioning member and cooperating with a guiding edge of the slide member, a rotary member movable about an axis of rotation and having a detection element for cooperation with the circumferential edge of the information carriers, and a servo element. The guide element is arranged on the rotary member, which is rotatably supported on the positioning member, the guide element being situated adjacent a straight line passing through the axis of rotation and the detection element, and the servo element being arranged on the slide member.
