Abstract

PURPOSE:To produce a magnetic recording medium having large coercive force by depositing a ferromagnetic metal and polymer simultaneously on a nonmagnetic substrate by a vapor deposition method, then subjecting the resultant medium to a heating treatment. CONSTITUTION:The film in which part of the polymer 300 intrudes among the particles of the columnar ferromagnetic metal 500 is obtd. if the ferromagnetic metal 300 and the polymer 500 are simultaneously deposited by evaporation on the nonmagnetic substrate 100. The polymer 300 which intrudes among the particles of the columnar ferromagnetic metal 500 and breaks the crystallinity of the ferromagnetic metal is removed and the crystallinity of the ferromagnetic metal is recovered if this medium is subjected to the heating treatment. The crystal magnetic anisotropy is thus increased and the coercive force is improved. The magnetic recording medium having the magnetic characteristics suitable as the magnetic recording medium is thereby obtd.
