Abstract
An apparatus for clamping an optical disc according to the present invention, if an optical disc loaded into a turntable of a spindle motor is clamped in an optical disc drive, keeps the clamper and the turntable of the spindle motor close to each other by using an elastic force delivered by an elastic member installed in an upper part of the clamper. Therefore, the present invention enables optical disc clamping operation and rotational operation of a spindle motor in a normal manner without employing an expensive magnet such as a clamper yoke, clamper magnet, and absorption magnet and thus efficiently reduces manufacturing costs of optical disc drives.
