ABSTRACT:
Magnetic recording media for high density recording having a much improved coercive force comprise a non-magnetic substrate and a magnetic thin film formed on at least one side of the non-magnetic substrate. The magnetic thin film consists essentially of a magnetic material and a tungsten oxide used in an amount of up to about 50 wt %, calculated as W, of the magnetic thin film. A method for making the media is also described.
