Abstract
An optical information recording mediumis constructed by sequentially layering a reflective layer, a protective layer, a recording layer, a protective layer, and a light transmissive protective layeron a substrate. As the recording layer, a recording layer containing ZnS, SiO, and Sb as principal components, or preferably, a recording layer expressed by a compositional formula [(ZnS)(SiO)](SbX)(where 0<x≦1.0, 0.3≦y≦0.7, and 0.8<z≦1.0 are met and X denotes at least one element selected from a group of Ga, Te, V, Si, Zn, Ta, and Tb) is adopted.
