发明名称 MANUFACTURING METHOD OF MAGNETIC RECORDING MEDIUM
摘要 PROBLEM TO BE SOLVED: To provide a magnetic recording medium excellent in corrosion resistance, while protecting a magnetic layer before filling a non-magnetic material from oxidization, and maintaining properties of the magnetic layer. SOLUTION: A manufacturing method of the magnetic recording medium includes: a pattern forming process which forms a pattern which is formed by alternately arranging a magnetic recording layer which records information and a groove which does not have a recording function on a disk substrate in which a soft magnetic layer is formed on a surface; an ALD process which performs by using the ALD method the deposition of a magnetic recording layer and an oxidization prevention layer on the surface of the magnetic recording layer and the groove of the disk substrate after the pattern forming process according to shapes of the magnetic recording layer and the groove; an non-magnetic material filling process which fills the groove of the oxidization prevention layer formed according to shapes of the magnetic recording layer and the groove with the non-magnetic material; and a smoothing process which exposes the magnetic recording layer by removing the non-magnetic material deposited on upper part of the magnetic recording layer and the oxidization prevention layer on the magnetic recording layer.
