PURPOSE:To enhance mass productivity and weatherability, by successively laminating a selenium layer, a tellurium layer and selenium layer to a substrate to provide a recording layer and setting the thickness of the selenium layer to 5-20Angstrom and the tellurium layer to 275-400Angstrom . CONSTITUTION:A selenium layer 2 with a thickness of 5-20Angstrom , a tellurium layer with a thickness of 275-400Angstrom and a selenium layer 4 with a thickness of 5-20Angstrom are successively formed to a substrate 1 by vacuum vapor deposition to form a recording layer to obtain an optical recording medium. As the substrate, a synthetic resin such as polycarbonate, polyolefin, polymethylpentene an acrylic resin or an epoxy resin or glass is used. Further, a layer formed of a separate substance, for example, a lead layer, a palladium layer or a magnesium layer can be inserted between the above-mentioned layers. |
