PURPOSE:To improve the running and wear resistance characteristics of a thin metallic film type magnetic recording medium, by providing a specific thin metallic film on a magnetic thin metallic film or the reverse side of a base. CONSTITUTION:On a base, such as a polyethylene terephthalate film, a ferromagnetic metallic layer is formed by vacuum deposition, etc., and on this ferromagnetic metallic layer or the base surface, a thin film of a metal in the IA, IB, IIA, IIB, IIIB, IVA, IVB, VA, VB, VIA, VIB, or VIIB group in the periodic table, such as Mg, Ca, Sr, Ba, Cu, Zn, Cd, Sn, and PB is provided. On the provided thin film, fatty acids, such as lauric acid, myristic acid, stearic acid, and oleic acid, are permitted to reside. |
