Abstract
An optical disc drive including a clamping mechanism, which faces a turntable, supports a surface of a disc, and is rotated. The clamping mechanism includes a clamper, which has access to the disc by a magnetic force when a spindle motor has access to the disc so that the disc is not deviated from a mounting portion when clamping is not completely performed, and a return member, which allows the clamper to be spaced apart from the disc as the spindle motor is spaced apart from the disc.
