PURPOSE:To improve running durability by providing a protective layer essentially consisting of specified graphitic carbon on a thin magnetic metallic film provided on a nonmagnetic substrate and providing a layer essentially contg. a fluorine lubricating agent further on the surface thereof. CONSTITUTION:The protective layer essentially consisting of the graphitic carbon contg. at least one kind selected from Cr, Mn, Mo, Nb, Ta, Ti, V, and W is provided on the thin magnetic metallic film provided on the nonmagnetic substrate. The lubricating layer contg. the fluorine lubricating agent is further provided on the surface of the protective layer. The recording medium formed in such a manner obviates generation of the materials sticking to a magnetic head, has nevertheless excellent lubricity and is improved in running durability.
