Abstract
PURPOSE: To increase the durability and acidproof characteristics by forming the film of macromolecular substance including specific silicone oil, on the surface of metal magnetic thin film including Co formed on the substrate of a magnetic recording medium.
CONSTITUTION: On the substrate of polyester film, the magnetic thin film of metal including cobalt such as cobalt-iron alloy is formed. Next, in forming the film of macromolecular substance consisting of one or two types selected from vinyl chloride copolymer, polyvinyl butyral copolymer and polymethyl methacrylate on the surface, the coefficient of friction of film can be reduced by containing the modified silicone oil taking the chemical compound as the major composition by 1W20wt% in this film as expressed in equation (at least one out of R1, R2 is -R3COOR4 and the rest is methyl, R3 is alkylene of C2WC20; R4 is H, CH3; m is 0W100; n is 1W100).
