摘要： A magnetic recording medium has an improved protective film covering a thin magnetic metal thin film provided on a non-magnetic support. The protective film consists of a plurality of layers formed by plasma polymerization, the base layer of which has a density of 0.7 to 1.5 g/cm.sup.3 and the surface layer of which has a density of not less than 1.2 g/cm.sup.3. This magnetic recording medium has good scratch resistance, weather resistance and abrasion resistance in addition to extremely small spacing loss. The magnetic recording medium can be produced by plasma polymerization of a wide variety of monomeric compounds.
