Abstract

PURPOSE:To improve both the corrosion resistance and the travelling performance, by adding an intermediate layer between a magnetic thin film and a photo-hardening resin layer. CONSTITUTION:A magnetic thin film of Co, Co-Fe, Co-Ni, etc. is provided on a substrate material 2 composed of a resin film; and an intermediate layer 11 composed of a nonmagnetic thin film of a metallic film of Cr, Ni-Cr, Fe-Cr-Si-B or Co-Fe-Si-B or an alloy film or a nonmagnetic thin film of a metallic film of Ta, Ti or Si or an oxide film of these elements is added. Furthermore a layer 10 composed of a photo-hardening resin such as vinyl cyclohexene diepoxide, 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexane carbonate and the like is provided on the film 11.
