ABSTRACT:
A magnetic recording medium having a thin magnetic metal film formed by vapor deposition under an atmosphere of an introduced oxygen gas. The thickness of the surface oxide film having the degree of oxidation of 50% or higher is maintained so as to be not higher than 5% of the total film thickness of the thin magnetic metal film. The magnetic recording medium is affected to a lesser extent by the surface oxide layer such that it is superior in magnetic properties, such as coercivity, and in electromagnetic properties.
