Title:
MAGNETIC RECORDING MEDIUM
Document Type and Number:
Japanese Patent JPH0652537
Kind Code:
A
Abstract:
PURPOSE: To provide a magnetic recording medium which is not deteriorated in saturation magnetization and can be increased in coercive force.
CONSTITUTION: The recording medium is constituted in such a way that an oxide layer 2 having a thickness of 5-100nm and partial oxide layer 3 of Co having a thickness of ≤150nm are successively formed on a high polymer substrate 1, with columnar particles in the layer 3 being inclined by ≥30° against a normal to the layer 3. Therefore, the coercive force of the recording medium can be increased without deteriorating the saturation magnetism of the medium.
