ABSTRACT:
To prevent an optical disc from being removed from a clamper even when an impact force is applied in an optical disc apparatus. A displacement amount by which a disc motor is sunk on the bottom case side is suppressed. In more detail, a convex portion which protrudes in the bottom cover direction is provided at a region including the whole or a part of an orthographically-projected surface of the disc motor on a surface of a bottom case opposed to a rear surface of the disc motor, and in a state of recording or reproducing, the sum of a distance between a motor fixing plate and a bottom cover and a distance between the bottom cover and the convex portion of the bottom case is smaller in the rotational axis direction of the disc motor than the sum of a distance between an optical disc and a tray and an insertion depth by which a clamper is inserted into a center hole of an optical disc.
