ABSTRACT:
An optical information recording medium that can simultaneously achieve both a high transmittance and high signal quality of an information layer, improve the reliability of long-term conservation, and reduce the manufacturing cost, and a manufacturing method thereof are provided. In an optical information recording medium including at least one information layer on a substrate, at least one of the information layers has a recording layer and a dielectric layer, the recording layer contains Te, O, and M (M is one or a plurality of elements selected from Au, Pd, and Pt) as major components, the dielectric layer has a thermal conductivity of 0.01 W/K·cm or more, and the dielectric layer has an extinction coefficient of 0 through 1.0 inclusive.
