    摘要： Techniques for reading and writing information onto a hard disk drive are provided. According to an embodiment of the present invention, a suspension assembly for a hard disk drive includes a load beam having a mounting region, a first spring extension on a first side of the load beam, and a rigid region. The suspension assembly also includes a hinge member having a second spring extension coupling the rigid region and the mounting region on a second side of the load beam. First and second spacers are disposed between the hinge member and the mounting region of the load beam and between the hinge member and the rigid region of the load beam, respectively. A vertical offset between the first and second spring extensions predisposes the rigid region to move from a first position to a second position in response to a disk flutter.

    摘要： The method of the present invention is capable of highly precisely producing a magnetic head. The method comprises the steps of: forming a pole end part of a magnetic layer, which becomes a magnetic pole and which is formed on a surface of a work piece on which the magnetic head will be formed, into a prescribed shape; coating at least a top part of the magnetic layer with a stopper layer; coating a surface of the work piece, on which the stopper layer has been formed, with an insulating layer, whose polishing rate is higher than that of the stopper layer; polishing the surface of the work piece until the stopper layer, which coats the top part of the magnetic layer, is exposed from the insulating layer; and removing the stopper layer, which has been exposed in a surface of the magnetic layer.

    摘要： On a single chip are formed a plurality of magnetoresistance effect elements provided with pinned layers having fixed magnetization axes in the directions that cross each other. On a substrate 10 are formed magnetic layers that will become two magnetic tunnel effect elements 11, 21 as magnetoresistance effect elements. Magnetic-field-applying magnetic layers made of NiCo are formed to sandwich the magnetic layers in plan view. A magnetic field is applied to the magnetic-field-applying magnetic layers. The magnetic field is removed after the magnetic-field-applying magnetic layers are magnetized in the direction shown by arrow A. As a result of this, by the residual magnetization of the magnetic-field-applying magnetic layers, magnetic fields in the directions shown by arrows B are applied to the magnetic layers that will become magnetic tunnel effect elements 11, 21, whereby the magnetization of the pinned layers of the magnetic layers that will become magnetic tunnel effect elements 11, 21 is pinned in the directions shown by arrows B.

    摘要： Embodiments include a method for forming a head suspension assembly. A spacer layer is formed in or on a silicon wafer. A transfer film including an opening defining the shape of a slider support membrane is provided, and the opening is filled with a resin material. The transfer film with the resin material therein is positioned over the silicon wafer so that at least a portion of the resin material is positioned adjacent to the spacer layer. The resin material is baked to form a glassy carbon material. The spacer layer is etched to form a trench in the silicon wafer adjacent to the glassy carbon material, and a slider is positioned on the glassy carbon material over the trench.

    摘要： A method of forming a magneto-resistive memory element includes forming a groove in a layer of insulating material. A liner is formed conformably within the groove and the groove is filled with copper and then planarized. The electrically conductive material is provided an upper surface that is recessed relative to the upper surface of the layer of insulating material. A cap, which can be conductive (e.g., Ta) or resistive (e.g., TiAIN), is disposed over the electrically conductive material and within the groove. A surface of the cap that faces away from the electrically conductive material, is formed with an elevation substantially equal to that of the edge of the liner, or the cap can extend over the liner edge. At least one layer of magneto-resistive material is disposed over a portion of the cap. Advantageously, the cap can protect the copper line from harmful etch processes required for etching a MRAM stack, while keeping the structure planar after CMP.

    摘要： A method of manufacturing magnetic heads comprises the step of: fabricating a magnetic head substructure by forming components of a plurality of magnetic heads on a single substrate, wherein a plurality of rows of pre-head portions that will be the respective magnetic heads later are aligned in the substructure; and fabricating the magnetic heads by separating the pre-head portions from one another through cutting the substructure. In the substructure first resistor elements and second resistor elements are formed. Each of the first resistor elements has a resistance that varies depending on the location of an end of an MR element located in a medium facing surface along the direction orthogonal to the medium facing surface. Each of the second resistor elements has a resistance that varies depending on the location of an end face of a track width defining portion located in the medium facing surface along the direction orthogonal to the medium facing surface. The medium facing surfaces are formed while monitoring the resistance values of the first and second resistor elements.
