ABSTRACT:
A magnetic recording medium with a magnetic thin film as a magnetic recording layer is described. The medium is comprised of a polymer support, a ferromagnetic metal thin film on the support, a plasma polymerization layer 20 to 270 .ANG. in thickness on the thin film, and a lubricating layer on the plasma polymerization layer. The lubricating layer is made of at least one member selected from compounds having a carbon-carbon unsaturated group at the terminal thereof and containing at least 8 carbon atoms. This magnetic recording medium is superior in corrosion protection, running properties, and durability, and moreover, has good electromagnetic properties.
