PROBLEM TO BE SOLVED: To develop anisotropy even in abase layer so as to add anisotropy to a magnetic layer by constituting a recording medium having a nonmagnetic substrate subjected to texture treatment along one direction, a seed layer, a base layer and a magnetic layer this order. SOLUTION: The seed layer 2 consists of, for example, Cr or a Cr alloy selected from a group of CrMo or the like, and the base layer 3 consists of a material selected from a group of NiAl, FeAl or the like. Te magnetic layer 6 consists of a material selected from a group of CoCrPt, CoCrPtB or the like. The (00) crystal plane of the seed layer 2 consisting of Cr or a Cr alloy is almost parallel to the upper face of the nonmagnetic substrate 1. By forming the aforementioned seed layer 2 between the nonmagetic substrate 1 and the base layer 3 having a B2 structure, the base layer 3 shows anisotropy, and the anisotropy can be added to the magnetic layer 6 formed thereon. |
