Provided is an optical disk drive including a turntable on which an optical disk is mounted and which rotates the optical disk, a chuck pulley movable in the direction of an axis of the turntable between a first pulley position spaced from the turntable and a second pulley position which is close to the turntable and in which the chuck pulley grips the optical disk together with the turntable, the chuck pulley being attracted toward the turntable by a magnetic force, and a pulley operating mechanism for moving the chuck pulley between the first pulley position and the second pulley position. The pulley operating mechanism, at the time of moving the chuck pulley between the first pulley position and the second pulley position, inclines the chuck pulley in relation to the turntable, and brings the chuck pulley closer to or away from the turntable.
