ABSTRACT:
An apparatus for clamping a disk comprises a clamper and a turntable. The clamper having a first cushion member is disposed on a bottom side of the clamper. The turntable is movably disposed relative to the clamper thereby clamping the disk between the turntable and the clamper. When the turntable is moved toward the bottom side of the clamper, one of the turntable and the disk touches the first cushion member first and then the clamper attaches to the turntable tightly for clamping the disk between the clamper and the turntable, therefore a striking force generated from the impact of one of the turntable and the disk on the clamper is reduced by the first cushion member.
