ABSTRACT:
A magnetic recording medium provided with a protective layer having excellent corrosion resistance and good adhesion is provided by a process which comprises forming a thin magnetic metal film on a nonmagnetic substrate by an oblique vapor deposition technique in a vacuum vessel, blowing an oxidizing gas against the surface of the thin magnetic metal film in the same vacuum vessel as used in the formation of the thin magnetic metal film, and thereafter forming a thin nonmagnetic metal film on the thin magnetic metal film.
