Abstract

PURPOSE:To shorten time for destructing data and to prevent the generation of environmental pollution by optically roughing the surface of plastic or the like used for the base material of an optical disk to disable data stored in the disk from being read out. CONSTITUTION:A jig 6 for roughing the surface of the optical disk 1 is constituted of a material, e.g. a file, for roughing the surface of the base material of the optical disk 1 made of plastic or the like stuck to a base 8. The jig 6 for roughing the surface of the optical disk 1 is inserted from a window 3 into a cartridge 2, and while contacting the jig 6 with the surface of the disk 1, the disk 1 is rotated to rough the surface of the disk 1. Since laser beams radiated to a recording film 4 in order to reproduce data are dispersed on the surface of the disk 1, the data can not be read out. Consequently, data can be disabled from being read out within a short time and a method for mechanically destructing the optical disk 1 is adopted to prevent the generation of a pollution problem.
