Optical recording medium

摘要

A recording medium comprises a substrate coated with a light reflecting layer which in turn is coated with a light absorbing layer selected from the group consisting of Pt complexes of bis-(dithio- alpha -diketones) which have the formula: wherein R is a phenyl or substituted phenyl group. During recording, portions of the absorbing layer are ablated, vaporized or melted by an intensity-modulated, focussed light beam, thereby exposing portions of the reflective layer and recording video information as a reflective-antireflective pattern.
