  • Publication number: 20070217067
    Abstract: The magnetic recording medium of the present invention has a substrate, a perpendicular magnetic recording layer, and a soft magnetic layer formed therebetween, having a thickness of less than 100 nm, the soft magnetic layer having a magnetic anisotropy in a surface direction, and product Bs·Hc, which is a production of a saturation magnetic flux density Bs and a coercive force Hc, of not less than 79 T·A/m (10 kG·Oe). By making the thickness of the soft magnetic layer into the above-mentioned range, the magnetic anisotropy in surface direction can be stabilized. magnetostatic energy can be increased sufficiently by making the Bs·Hc the above-mentioned range. Therefore, generating of the magnetic wall in the soft magnetic layer can be suppressed, the noise generating from the soft magnetic layer can be suppressed, and a high-density recording is enabled.
