  • Patent number: 7159302
    Abstract: A method for manufacturing a write head having a small write pole tip that emits magnetic flux sufficient for effective perpendicular recording. The method creates a leading edge taper (LET) between the write pole tip and a magnetic flux guide to create a sufficient magnetic flux in the write pole. The LET is fabricated by ion milling away a sacrificial striated material whose layers have different rates of ion milling. The top layer of material thus mills away faster than lower layers, creating the required tapering of a negative mold. An endpoint material stops the milling. The LET magnetic material is then spattered into the negative mold, resulting in a well defined taper of magnetic flux shaping material extending the magnetic flux guide to the write pole tip, such that the write pole tip is able to emit sufficient magnetic flux for perpendicular recording.

  • Patent number: 7159303
    Abstract: The magnetoresistance effect element is of a multilayered structure having at least magnetic layers and an intermediate layer of an insulating material, a semiconductor or an antiferromagnetic material against the magnetic layers, and the magnetoresistance effect element has terminals formed at least on the opposite magnetic layers, respectively, so that a current flows in the intermediate layer. The film surfaces of all the magnetic layers constituting the magnetoresistance effect element are opposed substantially at right angles to the recording surface of a magnetic recording medium. Therefore, the area of the magnetic layers facing the recording surface of the magnetic recording medium can be extremely reduced, and thus the magnetic field from a very narrow region of the high-density recorded magnetic recording medium can be detected by the current which has a tunneling characteristic and passes through the intermediate layer.

  • Patent number: 7146711
    Abstract: A method for forming a planar GMR read-head having a narrow read gap, a narrow track-width and being well insulated from its lower shield. The method requires the formation of a planarized bottom magnetic shield in which concave regions, symmetrically disposed about a track-width region, are filled with a layer of dielectric to provide added insulation. The dielectric filled shield is planarized and an additional planar dielectric layer, a thin planar GMR sensor layer and a planar PMGI layer of uniform thickness is formed on it. A layer of photoresist is deposited on the PMGI layer and a bi-layer lift-off stencil of uniform height above the GMR layer and symmetric overhang regions is formed. The uniformity of the lift-off stencil, which is a result of the planarity of the layers on which it is formed, allows the deposition of conductive lead and biasing layers with controlled overspread.

  • Patent number: 7146728
    Abstract: A method for selecting a resin or rubber material to construct an ink flow passage of an ink-jet recording apparatus includes immersing the resin or rubber material in water at 60° C. for 2 weeks in a tightly closed vessel, and determining an amount of eluted fatty acid derivative. If the amount of fatty acid derivative is not more than 20 ppm with respect to a total amount of the resin or rubber material, it is judged that the resin or rubber material is appropriate as the material for the ink flow passage. It is possible to select, by the convenient method, the material which is most suitable for the actual condition of use, without examining components and compositions of respective materials.
