ABSTRACT:
A magneto-optical recording medium comprises a dielectric film disposed on a substrate and formed, for example, of silicon nitride, of for example, 65 nm thickness, a magnetic film disposed on the dielectric film, and formed, for example, of, rare earth-transistion metal alloy thin film, of, for example, 35 thickness, and a reflective film disposed on the magnetic film, and formed of titanium nitride, by, for example, sputtering.
