ABSTRACT:
A magneto-optic memory device includes a transparent dielectric film of a non-oxygen containing nitride material deposited by sputtering on a substrate such as glass, a rare-earth/transition metal alloy recording medium deposited by sputtering on the dielectric film and a reflecting film deposited over the recording medium with or without an intervening transparent dielectric film of non-oxygen containing nitride material. This arrangement prevents the recording medium from being oxidized, and stablizes coercive force characteristics and information recording characteristics of the recording medium.
