Abstract: PURPOSE:To improve durability and to form thinner films by forming a plasma- polymerized protective film after a specific surface treatment with plasma. CONSTITUTION:A magnetic recording layer 12 of a CoCr film is deposited and formed on a nonmagnetic substrate 11 and the surface thereof is subjected to the treatment by oxygen (O2) plasma or the plasma treatment by a gaseous mixture composed of oxygen (O2) and argon (Ar), by which the contaminants on the surface are oxidized away. The surface is further subjected to the plasma treatment of the gaseous argon (Ar) and gaseous hydrogen (H2), by which the oxide layer is removed and the clean and activated surface is formed. The protective film 13 consisting of the plasma-polymerized film with a phenylic hydrocarbon as a monomer is formed on this surface. The adhesive strength of the film 13 to the layer 12 is enhanced in such a manner. Then, the durability of the film 13 is improved and the formation of the thinner films is facilitated.
