Magnetic recording medium

摘要

A magnetic recording medium has a non-magnetic metal base layer formed on a non-magnetic base and supporting a magnetic layer thereon. The non-magnetic metal base layer includes two or more base layers including at least one first base layer each having an anisotropic magnetic characteristic in which a coercive force in a circumferential direction of the magnetic recording medium is higher than a coercive force in a radial direction of the medium, and at least one second base layer each having an anisotropic magnetic characteristic in which the coercive force in the circumferential direction is lower than the coercive force in the radial direction.
