Process for intentional deterioration of the contents of an optical recording medium

A process for intentional degradation of information recorded in super-resolution in a structure for optical storage of high-resolution information, the structure comprising:

• a substrate equipped with physical marks whose geometrical configuration defines the information recorded, a superposition of three layers on top of the substrate marks, and a transparent protective layer on top of this superposition, the superposition comprising a layer of indium or gallium antimonide inserted between two dielectric layers of a zinc sulfide and silicon oxide (ZnS/SiO2) compound, the process comprising a degradation operation consisting in making a laser beam, which has a power around 30% lower than the power of the read laser used to read the information recorded in super-resolution on the disk, pass over the physical marks.
