ABSTRACT:
A method and apparatus for making an abrasion-resistant magnetic recording product comprising forming a magnetic film on the surface of a substrate in a vacuum container, and thereafter, vapor depositing a lubricant on the surface of the magnetic film in the same vacuum container. Preferably, the surface of the magnetic film can be oxidized with an oxidizing gas by ion bombardment in the same vacuum container, prior to vapor depositing the lubricant.
