Abstract

PURPOSE:To improve a traveling property, wear resistance and durability by forming specific perfluorosulfonate and specific lubricating agent successively by lamination on a magnetic layer. CONSTITUTION:A thin ferromagnetic metallic film 2 is formed on a nonmagnetic base 1. A 1st lubricating agent layer 3 contg. the perfluorosulfonate which is soluble in water and is hardly soluble in halogen base hydrocarbon and the 2nd lubricating agent layer 4 contg. the lubricating agent which is soluble in the halogen base hydrocarbon are successively formed on the thin ferromagnetic metallic film 2. A long-period lubricating effect is thereby maintained even under various usable conditions and the magnetic recording medium which exhibits the excellent traveling property, wear resistance, durability, etc., is obtd.
