ABSTRACT:
A process for the preparation of an optical recording medium, which comprises forming a thin optical recording film comprising at least one low melting point metal, carbon and hydrogen on a substrate, and heat treating the so formed film on said substrate at a temperature of from 70.degree. to 300.degree. C. for a period of at least 5 seconds. The optical recording medium so prepared has an enhanced recording sensitivity and a prolonged service life.
