An apparatus and method for testing mechanical endurance of a surface of an optical disc are disclosed. The apparatus includes a rotating plate, on which an optical disc to be scratched is loaded, for rotating the loaded optical disc, and a plurality of abrasion wheels of a predetermined type, disposed at a perpendicular to the rotating plate, for contacting the optical disc and generating the scratch, the scratch being generated when the optical disc rotates a predetermined number of turns, e.g., maximum of 5 turns for the abrasion wheels to apply a predetermined load on the optical disc. |
