PURPOSE:To improve durability by forming a thin ferromagnetic metallic film on a substrate, forming a film consisting of an org. compd. of a resin, etc. on the thin ferromagnetic metallic film and carbonizing the surface of the film by a method for implanting ions, etc. thereby providing a top coat layer consisting of the org. compd. having the carbonized surface. CONSTITUTION:The C-C bond on the film surface consisting of the org. compd. of the resin, etc. is severed by high energy ions and the carbonized amorphous carbon is formed when the ions are implanted to the film consisting of the org. compd. of the resin, etc. formed on the thin ferromagnetic metallic film layer by using an ion implanting device in a vacuum atmosphere. The carbonized layer is thus formed. The carbonized layer consisting of the amorphous carbon formed on the surface of the film consisting of the org. compd. of the resin, etc. is hard and has a lubricating function as well and therefore if the top coat layer consisting of the org. compd. formed with the carbonized layer on the surface is provided on the thin ferromagnetic metallic film layer, the wear resistance is improved and the durability is substantially improved. |
