摘要： A magnetic recording medium comprising a nonmagnetic substrate and a magnetic recording film of a magnetic metal material deposited through a primer layer of a nonmagnetic metal material on the substrate, wherein the primer layer is formed of a metallic material composed mainly of chromium or chromium and molybdenum and the magnetic recording film is formed of a metallic material composed mainly of at least one member selected from the group consisting of cobalt, chromium, tantalum, and platinum. The magnetic recording medium enables high-density recording by taking advantage of high coercive force and, at the same time, can reduce the noise level and improve the S/N ratio.
