Abstract
PURPOSE: To obtain a magnetic recording medium where film surface strength and the sliding property are improved, by vapor-depositing an organic lubricant and a high molecular material to the surface of the magnetic recording medium, where a ferromagnetic material vapor-deposition thin film is provided on a nonmagnetic material substrate, by the simultaneous vapor deposition method.
CONSTITUTION: A ferromagnetic material thin film consisting of a ferromagnetic metal such as Fe and Co, a magnetic alloy such as Fe-Co and Fe-Ni, an oxide magnetic material such as γ-Fe2O3 and Fe3O4, and so on is formed on a nonmagnetic material substrate consisting of polyethylene terephthalate, polyvinyl chloride, and so on by the vacuum vapor deposition method, the sputtering method, and so on. Next, organic lubricant (a) consisting of paraffinic hydrocarbon, a higher fatty acid, an oxy-fatty acid, fatty acid amide, fatty acid ester, fatty alcohol, metal soap, and so on and high molecular material (b) such as polyethylene and polypropylene are vapor-deposited to the surface by the simultaneous vapor deposition method.
