摘要:
A magneto-optical recording medium comprises a transparent substrate, a magneto-optical recording layer formed on the transparent substrate and containing a rare earth metal-transition metal alloy, and a thin film containing at least either one of platinum and palladium and formed at least on one surface of the magneto-optical recording layer. Or, the magneto-optical recording medium comprises the transparent substrate, and a magneto-optical recording layer formed on the transparent substrate by alternately overlaying a plurality of thin layers containing a rare earth metal-transition metal alloy, and a plurality of thin layers containing at least either one of platinum and palladium.
