OPTISCHES INFORMATIONSAUFZEICHNUNGSMEDIUM.

摘要

An optical information recording medium comprising: a light transmitting substrate (1); a light absorptive layer (2) overlaying the substrate to absorb a laser beam; and a light reflective layer (3) overlaying the light absorptive layer, wherein said substrate has a surface layer, adjacent to the light absorptive layer, which is deformable by energy generated upon absorption of the laser beam by the light absorptive layer, to form optically readable pits.
