    摘要： A media for perpendicular recording and a method of creating the media is provided. The media includes a hard recording layer and a soft underlayer (SUL). The SUL is composed of at least two anti-ferromagnetically coupled (AFC) sub-underlayers. The sub-underlayers respond to a magnetic field established during dynamic reversal with respective magnetic fields. The sub-underlayers are formed and disposed to differ in one or more magnetic moment, anisotropy, and thickness, so that their respective magnetic fields constructively interfere in one or more points in the hard recording layer, thereby reducing a total SUL magnetic field response to the dynamic reversal field approximately to zero at one or more points in the hard recording layer, which reduces side track erasure.

    摘要： Perpendicular magnetic recording media having no, or substantially reduced, Barkhausen noise are manufactured by a method comprising steps of: (a) providing a non-magnetic substrate having a surface; (b) providing the surface of the substrate with a unidirectional texture pattern; (c) forming an underlayer of a soft magnetic material over the unidirectional texture pattern, the layer of soft magnetic material having positive magnetostriction and uniaxial magnetic anisotropy and including a multiplicity of magnetic domains; and (d) forming a magnetic recording layer of a hard magnetic material over the underlayer; wherein the uniaxial magnetic anisotropy of the underlayer of soft magnetic material is sufficiently large to orient the magnetic domains thereof along the axis of the uniaxial magnetic anisotropy and thereby restrict domain wall formation and/or movement, whereby generation of Barkhausen noise in the soft underlayer is suppressed.
