An apparatus (46) for reconditioning a protective surface (30) of an optically-read digital recording disc (20) includes a turntable (48) configured to receive a center hole (24) of the disc (20) and a first motor (52), coupled to the turntable (48), for rotating the turntable (48) and the disc (20) at a first rotational speed. The apparatus further includes a buffing element (50) for removing an amount of material from the protective surface (30) as the turntable rotates the disc (20) and a second motor (54), coupled to the buffing element (50) for rotating the buffing element (50) at a second rotational speed. A timing element (56) synchronizes the first and second motors (52, 54) to substantially simultaneously cease rotation of the turntable (48) and the buffing element (50) following removal of an amount of material from the disc (20). The buffing element (50) includes a substantially rigid stabilizer plate (92) and a foam pad (88, 90) fixedly engaged with a plate surface (96) of the stabilizer plate (92). A buffing pad (82) is in fixed relation with the foam pad (88, 90). The buffing pad has a first surface (102) configured to face the foam pad (88, 90) and a second surface (104) configured to recondition the protective surface (30) of the disc (20).
