Optical information recording medium

Abstract

To obtain an optical information recording medium which is highly sensitive and excellent in durability against repeated recording and which is excellent in storage stability. An optical information recording medium is employed which comprises a substrate, a recording layer, a sulfur-containing protective layer, an interface layer in contact with the protective layer and a reflective layer in contact with the interface layer and containing Ag as the main component, wherein the interface layer contains Nb and/or Mo as the main component. By providing such an interface layer, the reaction between the reflective layer and the protective layer is effectively suppressed.
