Disclosed is an optical information recording medium which has an information layer having both a high transmittance and a high signal quality, has an improved reliability when stored for a long period and can be manufactured at a reduced cost. Also disclosed is a method for manufacture of the medium. The optical information recording medium comprises a substrate and one or more information layers provided on the substrate, wherein at least one of the information layers has a recording layer and a dielectric layer, where the recording layer comprises Te, O and M (wherein M represents at least one element selected from Au, Pd and Pt) as the main ingredients, and the dielectric layer has a thermal conductivity of 0.01 W/K.cm or higher and an extinction coefficient of 0 to 1.0 inclusive. |
