ABSTRACT:
The recording sensitivity can be improved of a magneto-optical recording medium having a laminar structure consisting of a first dielectric layer, a recording layer, a second dielectric layer and reflecting layer successively formed on a transparent substrate plate by forming the reflecting layer from an alloy consisting of aluminum and from 0.05 to 3 atomic % of a rare earth element such as neodymium and gadolinium in place of pure aluminum as in conventional magneto-optical recording media.
