Abstract

A write once optical recording medium includes a substrate on which an oxide film 3 constituting an inorganic recording film is formed, the oxide film 3 being made of a recording material of an oxide Ge (x is an atomic number ratio) of germanium (Ge) and a composition of Gex of the oxide film being specified so as to satisfy 1.0 < x < 2.0. Recording and reproducing characteristics of the write once optical recording medium can be improved and an arrangement of this write once optical recording medium can be simplified.
