| abstract | (57) [Abstract] [Purpose] In a magneto-optical recording medium, the environmental resistance is improved by protecting the recording film from oxidation by oxygen and moisture that have passed through the protective film. A disc-shaped magneto-optical recording medium having a multi-layered recording film formed on a substrate by a sputtering method, which includes a transparent dielectric protective layer, a magnetic recording layer, and a reflective layer. The magneto-optical recording medium, wherein the ratio of the rare earth metal in the recording layer is high near the interface with the dielectric layer. [Effect] By increasing the ratio of the rare earth metal in the portion of about 1 to 2 nm from the interface of the recording layer to the dielectric layer to be larger than that inside the recording layer, the progress of oxidation inside the recording layer is prevented and the environmental resistance is improved. be able to. |
