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.

Abstract: The present invention is related to a tray of an optical disc drive. In a tray according to one embodiment of the present invention, a flutter hole is formed in the middle of the tray providing space through which an optical pick-up moves toward an inner or outer circumferential area of an optical disc and a guide vane is formed to prevent contamination of the optical disc caused as grease spread on a lead screw of a sled motor for moving the optical pick-up moves according to air flow due to rotation of the optical disc. The guide vane can be formed only in a surface in which the lead screw is installed among two vertical side surfaces forming a boundary of a flutter hole of the tray and the guide vane can be formed at a position corresponding to an outer circumferential area of the optical disc.
