Abstract

PURPOSE:To obtain a magnetic recording medium with excellent wear resistance and running property, by providing a layer of fatty acid ester having >=35 deg.C melting point on a magnetic metallic thin film. CONSTITUTION:A magnetic metallic thin film made of ferromagnetic metal or alloy such as cobalt and nickel is formed on a vase with a vapor deposition method or a plating method. Further, fatty acid ester (stearic acid methyl ester, nonandecanoic acid methyl ester, arachic acid methyl ester, behnic acid methyl ester, lauric acid octadecyl ester, palmitic acid pentadecyl ester, behelic acid octyl ester and other fatty acid ester) expressed in general formula of R1COOR2 (Where; R1 and R2 are alkyl group) having >=35 deg.C melting point is coated on the surface to form a magnetic recording medium.
