Optical information recording member.

摘要

An optical information recording member is disclosed comprising a thin film (17) formed on a substrate (16). The thin film is made of TeOx (a mixture of Te and TeO2) with a small amount of Au being added. Further, a thermal diffusion layer (18) of a metal having a higher heat conductivity than the thin film may be formed on at least one side of the recording thin film (17). …In consequence, undesirable distortion of the recording bits is prevented even when an excessively large recording power is irradiated.
