Perpendicular magnetic recording medium and manufacturing method thereof.

摘要

A perpendicular magnetic recording medium free from spike noise having a high permeability magnetic material film (2), an antiferromagnetic material film (6) and a perpendicularly oriented magnetic material film (3) formed on a substrate (1) in this order. Another high permeability magnetic material film (9) may be formed between the antiferromagnetic material film and the perpendicularly oriented magnetic material film. During the formation of the antiferromagnetic material film (6), a magnetic field is applied in a direction of a track width.
