  • PERPENDICULAR MAGNETIC RECORDING FILM MEDIUM AND METHOD OF MANUFACTURING THE SAME
    Publication number: 20090092858
    Abstract: The perpendicular magnetic recording medium of the present invention includes a substrate, a non-magnetic layer, a ferromagnetic layer and an antiferromagnetic oxide. The non-magnetic layer is formed on the substrate and the ferromagnetic layer is formed on the non-magnetic layer. The antiferromagnetic oxide is formed in the ferromagnetic layer after the perpendicular magnetic recording medium is annealed by an annealing process. An exchange coupling interaction between the antiferromagnetic oxide and the ferromagnetic materials is introduced.
