ABSTRACT:
A magnetic recording medium includes a nonmagnetic underlayer, an initial magnetic layer, a nonmagnetic spacer layer provided on the initial magnetic layer, and a final magnetic layer provided on the nonmagnetic spacer layer. The initial magnetic layer is disposed closer to the nonmagnetic underlayer than the final magnetic layer, and the initial and final magnetic layers are made of mutually different compositions and are anti-ferromagnetically coupled.
