Abstract
This invention relates to a magnetic recording medium in which a protective film prepared by plasma polymerization of an organic compound such as dibenzyl or diphenyl which exhibits a solid phase at room temperature and under atmospheric pressure is formed on a thin ferro-magnetic film. This invention also relates to a method of manufacturing the magnetic recording medium. The protective film has a high wear resistance and excellent anti-corrosion properties.
