Abstract

PURPOSE:To realize the vertical magnetization recording with use of a Co-Cr alloy thin film and without any lowering of the short wavelength output, by using an amorphous soft magnetic thin film as a substrate soft magnetic layer. CONSTITUTION:At least one of the transition metals Fe, Co, Ni, etc. plus an amorphous soft magnetic thin film composed of a semimetal such as Si, B, P, C, etc. are provided on a substrate of polyimide film, etc. In addition, an alloy thin film layer having a magnetization facilitating axis in the direction vertical to the surface of a recording medium composed of Co-Cr is provided on the above-mentioned amorphous soft magnetic thin film.
