    摘要： A perpendicular magnetic recording medium with antiferromagnetic coupling in a soft magnetic underlayer. The soft magnetic underlayer includes a first magnetic soft layer, a first interface layer on the first magnetic soft layer, a second magnetic soft layer, a second interface layer on the second magnetic soft layer, and a non-magnetic coupling layer between the first interface layer and the second interface layer. The first and second magnetic soft layers are antiferromagnetically exchange coupled to one another through the non-magnetic coupling layer, wherein the first and second interface layers increase the exchange coupling between the first and second magnetic soft layers.

    摘要： A perpendicular recording head for use with magnetic recording medium has an improved structure permitting an unusually narrow trackwidth to be defined by a simple, cost-efficient manufacturing process. The main pole and opposing pole of the recording head are deposited on the side of the slider, so that the trackwidth is controlled by the thickness of material deposited to form the main pole. The dimension of the main pole along the direction of the track is not critical for permitting a recording head of the present invention to record at high densities. The opposing pole may be located in front of, to the side of, or behind the main pole.

    摘要： The present invention provides perpendicular recording media having a soft magnetic underlayer and magnetic regions which generate an external magnetic field in the soft magnetic underlayer. The soft magnetic underlayer is brought into a substantially single-domain state by the magnetic field, thereby reducing or eliminating unwanted noise in the soft underlayer. In a preferred embodiment, the recording medium includes a ring-shaped soft magnetic underlayer positioned between concentric ring-shaped magnetic regions.

    摘要： Embodiments of the present disclosure provide a method for selective removal of atoms from a substrate. Such a method comprises forming a patterned mask over at least a portion of the surface of the substrate to form a masked portion and an unmasked portion of the surface. In an embodiment, the method comprises exposing the surface to low energy light ions. In a related embodiment the low energy light ions selectively remove atoms from the unmasked portion of the substrate. In some embodiments, the method further comprises removing the mask.In another embodiment, the present disclosure relates to a method of creating a plurality of magnetic domains on a magnetically susceptible substrate. In an embodiment, the present disclosure pertains to a method of forming a magnetic medium.
