PURPOSE: A clamper for optical drive is provided to attach a disk to a turntable perfectly by installing wing members for converting an inflow air into pneumatics with a direction in which a base is pushed. CONSTITUTION: A spindle motor(5) operates a disk(4). A clamper(20) attaches and fixes the disk(4) to a turntable(6) by a magnetic force generated from pneumatics and a magnet(22). The clamper(20) has a pin(21) for adapting a concentric to the turntable(6), a base(23) for pushing the disc(4) toward the turntable(6), a magnet(2) for generating the magnetic force, and a plurality of wings(24) for generating pneumatics in a direction in which the base(23) is pushed when rotating the disk(4). A disc adhesive surface(23a) is projected to a bottom surface as a ring band and is attached to the disk(4). The disc adhesive surface(23a) is formed at the base(23).
