ABSTRACT:
The present invention provides a disc drive apparatus that can effectively prevent the part of the flexible printed circuit board that cannot be covered by the top cover from coming out to the outside through the aperture of the top cover when the flexible printed circuit board displaces its folded position, following the movement of the optical pickup that is being fed. The disc drive apparatus includes a cabinet, a disc drive unit contained in the cabinet, and a circuit substrate carrying a drive control circuit for controlling the operation of driving the disc drive unit. The disc drive unit includes a disc rotary drive mechanism, an optical pickup, a pickup feed mechanism, a base, a flexible printed circuit board, and a top cover. The disc drive unit is structurally so adapted as to hold down the lateral edge section of the flexible printed circuit board rising to a greater extent than the other lateral edge section as viewed in the longitudinal direction thereof at least at the folded position thereof while the flexible printed circuit board displaces the folded position, following the movement of the optical pickup being fed.
