Abstract: A low-profile chucking mechanism holds a disc recording medium on a turntable that has a plurality of first engaging teeth and a plurality of second engaging teeth. When the disc recording medium is to be mounted on a disc supporting surface of the turntable, the first engaging teeth are pushed radially inwardly of the rotational axis of the turntable by the edge of a central circular hole of the disc recording medium. When the first engaging teeth are moved, the second engaging teeth are biased in ganged relation to the first engaging teeth radially outwardly of the rotational axis of the turntable and engage the edge of the central circular hole of the disc recording medium mounted on the disc supporting surface, thereby pressing and holding the disc recording medium against the disc supporting surface.
