  • Patent number: 9283651
    Abstract: An electrical lapping guide has a body with a thickness along a wafer axis, the body comprising a layer of conductive material having a resistivity. The conductive material layer comprises a first contact region and a second contact region, the first and second contact regions configured to electrically connect the electrical lapping guide to electrical leads. A lapping edge comprises an air-bearing plane axis perpendicular to a lapping axis, and a back edge opposite the lapping edge, the back edge comprising a plurality of notches.

  • Patent number: 9087530
    Abstract: A transducer having an external contact surface includes a writer and a contact member. The writer has a portion extendable relative to an adjacent portion of the external contact surface. The contact member surrounds at least a portion of the extendable writer portion and is spaced from the extendable writer portion. The coefficient of thermal expansion of the contact member is approximately equal to the coefficient of thermal expansion of the extendable writer portion.

  • Patent number: 7573682
    Abstract: A transducing device having a storage interface surface includes a writer having a pole tip region, a coil having a width positioned around the writer, and a heating element. The heating element extends to near the storage interface surface. A portion of the heating element is at least as wide as the coil. The heating element heats the writer in response to current flow through the heating element.

  • Patent number: 7411264
    Abstract: The present invention provides a thin-film structure that includes an etch-stop layer having a first side and a second side, a patterned compensation layer for dissipating thermal energy, and an etch-vulnerable layer, where the etch-stop layer substantially impedes etching. The patterned compensation layer is adjacent the first side of the etch-stop layer, and the etch-vulnerable layer is adjacent the second side of the etch-stop layer.

  • Patent number: 7207098
    Abstract: A method of forming a reader of a magnetic head includes multiple processing steps. First, a sensor is formed having an air bearing surface. Next, a hard mask is formed on the sensor extending a distance from the air bearing surface substantially equal to the desired stripe height of the sensor. Finally, a portion of the sensor not covered by the hard mask is removed.
