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 (Al) and from 0.05 to 10 atomic % of a rare earth element such as neodymium (Nd) and gadolinium (Gd) in place of pure aluminum as
