INITIAL MAGNETIZING METHOD OF MAGNETIC RECORDING MEDIUM, MAGNETIC TRANSFER METHOD AND MAGNETIC RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a method for collectively initially magnetizing a coating type magnetic medium. SOLUTION: In this initial magnetizing method of a magnetic recording medium in which an initialization magnetic field is impressed in the circumferential direction of a disk-shaped magnetic recording medium with a magnetic layer formed by applying a magnetic body to one side or both sides of a support to initially magnetize the magnetic recording medium in one direction of the circumferential direction, when the coercive force of a magnetic layer constituting the magnetic recording medium is Hc, the magnetic field Hdp of a component parallel with the surface of the magnetic recording medium in an initialized magnetic field is 2.2×Hc
