ABSTRACT:
A data recording medium comprising, as a recording layer, a thin magnetic alloy film having an axis of easy magnetization along a direction perpendicular to the surface thereof, and an anticorrosion protective layer formed on the recording layer. This recording medium is featured in that the anticorrosion protective layer is formed of a thin oxide film which is obtained by subjecting the surface portion of the recording layer to an anodic oxidization. This protective layer may be further covered with a dielectric film as a second protective covering.
