摘要： In a magnetic recording medium wherein a metal thin film magnetic layer and a topcoat layer of an organic fluorine compound are formed on a nonmagnetic substrate, the surface of the magnetic layer is plasma treated or plasma oxidized, enhancing the bond between the adjoining layers. A protective film of carbon may be disposed between the magnetic layer and the topcoat, with the surface of the protective carbon film plasma treated. Instead, a protective film of plasma-polymerized organometallic compound may be used.

摘要： The present invention improves the adhesive property by pretreating under uniform conditions the substrate surface of metal, ceramics or glass etc. with a poor adhesive property, by accelerating ions under an electric field to the substrate in advance of a diamond-like film forming process. In light of the fact that a diamond-like film forming process by ionized deposition uses thermal electron ionization means and an electric potential is applied to a grid to accelerate ionized hydrocarbon ions, the present invention could attain the aimed purpose by ionizing and then accelerating a bombardment gas such as argon as a pretreatment process in the same apparatus.
