  • Patent number: 8993071
    Abstract: Embodiments of the present invention provide a manufacturing method that can form a track guide separation area of a magnetic disk substrate constituting a patterned medium represented by a discrete track medium or bit patterned medium suitable for high recording density, uniformly on the whole surface of the magnetic disk substrate, and accurately according to the mask. According to one embodiment, a soft magnetic film, an under coating film, and a magnetic film are formed on a substrate. A mask having an arbitrary pattern shape provided for forming the track guide separation area in the magnetic film is formed on the magnetic film, and the track guide separation area is formed by irradiating ions and electrons onto the surface of the magnetic film and applying an intermittent voltage to the substrate, thereby non-magnetizing the area irradiated.

  • Patent number: 8383253
    Abstract: Embodiments of the present invention produce discrete track media and bit patterned media having both excellent read/write performance and reliability. According to one embodiment, the medium comprises a magnetic layers formed by at least two ferromagnetic alloy layers with different compositions on a substrate. The ferromagnetic alloy layer located closest to the medium surface has more concentrated parts and less concentrated parts of nonmagnetic element in the in-plane direction. The more concentrated parts of the nonmagnetic element contain more nonmagnetic elements than the other parts except for an intermediate layer in the magnetic recording layer. The more concentrated parts and the less concentrated parts of the nonmagnetic element in the ferromagnetic alloy layer located closest to the medium surface are formed substantially concentric. The more concentrated parts of the nonmagnetic element is formed by being doped with ions of nonmagnetic element.

  • Patent number: 8257845
    Abstract: Embodiments of the present invention help to produce discrete track media and bit patterned media having both excellent recording and reproducing performance and reliability. According to one embodiment, a manufacturing method forms a nonmagnetic layer mainly composed of the same element as a nonmagnetic element contained in magnetic recording layers and on the magnetic recording layers and a mask layer having apertures for forming more concentrated parts of the nonmagnetic element in the magnetic recording layers on the nonmagnetic layer. The method implants ions of the nonmagnetic element through the nonmagnetic layer masked by the mask layer to form the more concentrated parts of the nonmagnetic element in the magnetic recording layer.
