DISC CLAMPING DEVICE AND OPTICAL DISC DRIVE INCLUDING THE SAME

摘要

PURPOSE: A disc clamping device and an optical disc drive including the same are provided to securely clamp a disc mounted on a turn table using centrifugal force caused by the rotation of the turn table. CONSTITUTION: A disc clamping device of an optical disc drive is installed at a boss(330) with a predetermined height inserted into a center hole(H) of a disc(D) to clamp the disc mounted on a turn table(120). The disc clamping device includes a clamper(340) and a spring(350). The clamper clamps the disc in such a manner that one end of the clamper is connected with the boss by a hinge and the other end is rotated by centrifugal force generated from the rotation of the turn table. The spring is combined with the other end of the clamper to elastically bias the other end of the clamper to be placed inside the boss.
