Apparatus and method for testing mechanical endurance of surface of optical disc, the optical disc of same kind as the tested optical disc

摘要

An apparatus and method for testing mechanical endurance of a surface of an optical disc is disclosed, which includes a rotating plate on which the optical disc is fixed to generate scratch thereon, and rotating the fixed optical disc; and a plurality of abrasion wheels disposed in perpendicular to the rotating plate, and being in contact with the surface of the optical disc, to generate the scratch on the surface of the optical disc, wherein, the scratches generate when the optical disc rotates a predetermined turn, e.g. below ten turns for applying a predetermined load generated from the abrasion wheel on the optical disc.
