ABSTRACT:
An optical information recording material which comprises a substrate having thereon a heat mode recording layer made of a metal and a metal compound that increases the sensitivity of said recording layer and decreases the reflectivity of said recording layer, a reflecting layer made of a metal, and a heat insulating layer interposed between said recording layer and said reflecting layer. The material makes it possible to record information at high sensitivity and read recorded information by reflected light at high contrast.
