Abstract
PURPOSE:To manufacture a film having a superior perpendicular magnetic properties and also having high magnetic recording density, by alternately laminating Co and Cr on a substrate in super vacuum. CONSTITUTION:The degree of vacuum in a vacuum chamber 6 in the course of vapor deposition is maintained at 10<-8>Torr or above. In this atmosphere, Co and Cr are alternately vapor-deposited and laminated on a substrate, by which a perpendicular magnetic recording film is formed. In this alternately laminated film 13, respective columnar-crystal grains of the above two elements grow in uniform thickness from the substrate 10 toward the film surface, and further, the degree of crystal orientation of this film is comparatively independent on the size of columnal crystalline grain and C axis is sharply oriented owing to the magnitude of the value. Accordingly, magnetic recording density can be improved without deteriorating magnetic properties.
