DEVICE FOR EXAMINING MECHANICAL DURABILITY OF OPTICAL DISK SURFACE AND METHOD THEREFOR, CONCERNED WITH MORE INCREASING DATA PRESERVATION WHILE ENHANCING RELIABILITY

摘要

PURPOSE: A method for examining the mechanical durability of an optical disk surface is provided to quantify scratch generation information to improve surface mechanical properties, and to easily examine the quality of an optical disk, thereby more increasing data preservation while enhancing reliability. CONSTITUTION: A rotative plate(20) puts an optical disk(30) on which a scratch is generated, and rotates the optical disk(30) through a rotary motion. Plural abrasion wheels(10) are formed in a vertical position to the rotative plate(20), and generate the scratch through the rotation of the rotative plate(20) by a preset load on a surface of the optical disk(30) in contact with the optical disk(30). Predetermined scratch patterns are formed on the optical disk(30) by the abrasion wheels(10) contacted according to the preset load and the preset number of revolution.
