    摘要: An object of the present invention is to provide an optical recording medium which exhibits high storage reliability in high-temperature/high-humidity conditions, stable performance at high temperatures, appropriate mechanical properties and high productivity and is capable of reproducing and recording at high speeds. It is an optical recording medium containing a lower protective layer, an optical recording layer, an upper protective layer and an optical reflective layer which contains 98% by weight or more of Ag that are formed on the substrate, the thickness of the optical recording layer is 8 nm to 14 nm and the thickness of the upper protective layer is 4 nm to 24 nm, the upper protective layer contains at least one of zinc oxide, indium oxide, tin oxide, niobium oxide, silicon nitride, aluminum nitride and SiOx (1.6≦x≦1.9) and less than 0.1% by weight of at least any one of sulfur and chlorine, and the upper protective layer is amorphous after recording or rewriting.
