ABSTRACT:
The ceiling board of the cabinet of a disc drive apparatus has an abutment projection arranged at a position located vis-à-vis and projecting toward the turntable. The main surface of the abutment projection opposite to the main surface located vis-à-vis the turntable is supported by a top surface supporting section formed on the frame. With this arrangement, when the turntable is raised to the chucking position, the optical disc is pressed by the abutment projection of the ceiling board supported by the protruding section of the top surface supporting section at a part thereof surrounding the center hole of the optical disc so that the engaging projection is engaged with the center hole of the optical disc and the optical disc is held on the turntable in a state where the optical disc is anchored by a plurality of anchoring sections at a part thereof surrounding the center hole of the optical disc.
