A higher value of anisotropic magnetic field can be acquired by using a magnetic material where Cr is not added as a material of a magnetic layer on which magnetic data is recorded. A magnetic recording medium (1) can be manufactured through the processes of laminating an underlayer (3) consisting of Cr-based non-magnetic material on a substrate (2) and then laminating, on this underlayer, a magnetic layer (4) consisting of an alloy of at least a kind of non-magnetic material different from Cr and Co.
