Process for preparation of optical recording medium.

摘要

A process for the preparation of an optical recording medium is disclosed, 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 DEG to 300 DEG 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.
