Abstract

PURPOSE: To make it possible to produce a magnetic recording medium, which is constituted by using a hexagonal high-coercive force magnetic thin film, with a good yield by providing previously a specific hexagonal magnetic layer on a nonmagnetic support substance.
CONSTITUTION: The normal direction of nonmagnetic support substance 11 is inclined or the incident direction of evaporated particles, and hexagonal nonmagnetic layer 12 such as Ti is formed in a forming speed over 2,000Å/min so that C axis components may be much included in parallel with the face of substance 11. On this layer 12, hexagonal magnetic thin film 13 such as Co is laminated with the incident angle near to angle 0.
