摘要

A recording medium comprises a substrate 110 coated with a light reflecting layer 112 which in turn is coated with a light absorbing layer 114 consisting of a Pt complex of bis- (dithio- alpha -diketones) which have the formula: IMAGE wherein R is a phenyl or substituted phenyl group. During recording, portions 116 of the absorbing layer 114 are ablated, vaporized or melted by an intensity-modulated, focussed light beam, thereby exposing portions of the reflective layer 112 and recording video information as a reflective-antireflective pattern.
