Abstract: PURPOSE:To improve the travelling durability of a magnetic recording medium and the oxidation resistance of a thin ferromagnetic metallic film when the metallic film contg. oxygen is formed on a nonmagnetic supporting body to produce the medium, by treating the surface of the metallic film with alcohol contg. a specified amt. of water and by forming a protective film of an org. compd. on the metallic film. CONSTITUTION:The surface of a thin ferromagnetic metallic film formed on a nonmagnetic supporting body is treated with alcohol contg. 1-80wt.% water and a protective film of an org. compd. is formed on the metallic film. Inorg. foreign matter is removed from the surface of the metallic film chiefly by the physical detergency of the solvent, water soluble and oil soluble org. foreign matters are removed by the chemical detergency and the surface of the metallic film is activated by partial conversion into oxide or hydroxide. Since the protective film is formed on the clean activated surface of the metallic film, the protective film adheres firmly to the metallic film, improving the travelling durability of the resulting magnetic recording medium and the oxidation resistance of the metallic film.
