Abstract
PURPOSE: To improve film surface strength and a sliding property, by vapor-depositing an organic lubricant, which can be vapor-deposited, to the surface of the magnetic recording medium where a ferromagnetic material vapor deposition thin film is provided on a nonmagnetic material substrate.
CONSTITUTION: A ferromagnetic material thin film consisting of a ferromagnetic metal such as Fe, Co and Ni, a magnetic alloy such as Fe-Ni and Co-Ni, or an oxide magnetic material such as γ-Fe2O3, Fe3O4 and CrO2 is formed on a nonmagnetic material substrate consisting of polyethylene terephthalate or polyvinyl chloride by the vacuum vapor deposition method, the sputtering method, and so on. Further, an organic lubricant consisting of a paraffinic hydrocarbon such as parrafin and microwax, a higher fatty acid such as lauric acid and myristic acid, an oxy-fatty acid, fatty acid amide, fatty acid ester, fatty alcohol, metal soap, and so on is provided on the surface by vapor deposition.
