Abstract

PURPOSE:To improve an abrasion-resistant property and a corrosion resistant property, by coagulating, polymerizing and cross-linking ionized monomer vapor on a ferromagnetic metallic thin film, and forming a protective layer. CONSTITUTION:A film basic material 6 is moved to a take-up roll 12 from a feed roll 7, and also a ferromagnetic metallic thin film is formed by a ferromagnetic metal or alloy from an ion beam source 13 by means of vapor deposition. Subsequently, a film on which said ferromagnetic metallic film has been formed by means of vapor deposition is led to a drum 11, an organically polymerizable monome which is jetted from a fine pipe nozzle is ionized by a coillike high frequency electrode, is made incident to the ferromagnetic metallic thin film, and an organic polymer thin film which has been cross-linked in a high level is obtained.
