PURPOSE:To obtain the medium which obviates the degradation of reflectivity and substantially prevents the spread of recording pits by successively forming a reflecting film in a fine crystalline or amorphous state essentially consisting of Te and an inorg. oxide film directly or via an inorg. oxide film on a substrate. CONSTITUTION:The reflecting film 2 is formed on the substrate 1. The reflecting film which consists essentially of the Te, is incorporated with >=1 kinds of the elements selected from the prescribed group of Al, Si, Ti, etc., in a prescribed range and is in the fine crystalline or amorphous state is used for the reflecting film 2. The inorg. oxide film consisting of glass, SiO2, etc., are formed thereon. The medium which obviates the degradation of reflectivity and substantially prevents the spread of the recording pits is obtd. in this way. |
