PURPOSE:To enhance resistance to abrasion and humidity, etc., by forming a fluorine-contg. plasma polymn. film on a continuous thin film type magnetic layer. CONSTITUTION:A ferromagnetic continuous thin film of a Co type is formed on a nonmagnetic base by the vapor deposition, sputtering, ion plating, or the like, and on this layer a polymn. film is formed by plasma polymn. using one or a combination of tetrafluoroethylene, 2,2,2-trifluoroethanol, 2,2,3,3-tetrafluoro-1- propanol, ethyl trifluoroacetate, 2,2,3,3,4,4,5,5-octafluoro-1-pentanol, trifluoroacetylacetone, perfluoromethyleychlohexane, or perfluoroheptane, and the like fluorine-compd. monomer. |
