Optical information recording medium

摘要

An optical information recording medium comprising a substrate and a recording layer superimposed on said substrate, said recording layer comprising a reflective layer in which metal particles with a particle diameter of 1500 ANGSTROM or less have been distributed closely and a light absorptive layer in which metal compounds and a very small amount of metal particles with a particle diameter of 200-2000 ANGSTROM have been dispersed unformly or substantially uniformly in the volume ratio of 1-30% in a resin.
