Patent ID: 8679654

Claim:
A magnetic recording medium including a non-magnetic substrate and at least a magnetic recording layer formed thereon, wherein the magnetic recording layer comprises a plurality of magnetic layers each including a magnetic alloy whose principal material is Fe and Pt and at least one non-magnetic material selected from the group consisting of carbon, oxide and nitride, a first magnetic layer disposed at a layer relatively close to the substrate has a granular structure in which magnetic alloy grains including an FePt alloy as a principal material are separated from grain boundaries including the non-magnetic material as a principal material, and a second magnetic layer disposed closer to a surface than the first magnetic layer and has a homogeneous non-granular structure in which an FePt alloy and the non-magnetic material are mixed with each other in a state of mixture finer than diameters of the FePt magnetic alloy grains in the first magnetic layer.
