Abstract

PURPOSE:To improve the corrosion resistance, by making a magnetic recording medium vapor deposited with a slope to a base, and from the direction of normal. CONSTITUTION:A magnetic substance of an evaporation source 1 is evaporated in a vacuum tank with a tilt angle theta1 to a base 3 supported on a support stand 4, and gaps among crystals are burried by vapor depositing a non-magnetic substance such as SiO from almost the normal in angle theta1 from a heat source 2. Thus, the corrosion resistance is improved.
