摘要： A magnetic recording medium having a thin magnetic metal film formed on a non-magnetic base is disclosed. A thin film of a copolymer having vinylidene chloride and acrylonitrile as repeating units is formed on either the thin magnetic metal film or the surface of the base opposite the thin magnetic metal film or both. The resulting magnetic recording medium has improved running properties, wear resistance and electro-to-magnetic conversion characteristics.
