Abstract
PURPOSE: To improve film surface strength and sliding property, by exposing the magnetic recording medium, where a ferromagnetic material vapor deposition thin film is provided on the nonmagnetic material substrate, to vapor of an organic lubricant.
CONSTITUTION: Ferromagnetic material thin film 2 consisting of a ferromagnetic metal such as Fe, Co and Ni, a magnetic alloy such as Fe-Co, Fe-Ni and Co-Ni, an oxide magnetic material such as γ-Fe2O3, Fe3O4 and CrO2, a nitride magnetic material such as Fe3N, and so on is formed on nonmagnetic material substrate 1 consisting of polythylene terephthalate, polyimide, polyvinyl chloride, and so on by the vacuum evaporation deposition method, the sputtering method, or the reactive vapor deposition method. Next, this magnetic recording medium is exposed to vapor 6 of organic lubricant 5 obtained by heating fatty acid hydrocarbon, higher fatty acid, oxy-fatty acid, fatty acid amide, fatty acid ester, fatyalcohol, metal soap, and so on at the boiling point, the sublimation point, or a temperature of the decomposition point or less.
