  • Double shell writers
    Patent number: 8649124
    Abstract: An apparatus illustratively includes a return pole (RP) and a shield. The RP has a first RP magnetic layer, a second RP magnetic layer, and a RP non-magnetic layer. The RP non-magnetic layer separates and magnetically decouples the RP first and second magnetic layers. The shield has a first shield magnetic layer, a second shield magnetic layer, and a shield non-magnetic layer. The shield non-magnetic layer separates and magnetically decouples the shield first and second magnetic layers. A method illustratively includes generating magnetic flux and collecting the magnetic flux through an inner magnetic shell.

  • Transducer including an element of a transducer and a sidewall in an electrically conductive magnetic layer
    Publication number: 20070177300
    Abstract: A transducer includes a first layer that is selectively deposited in a contact region to form a core, and selectively deposited in a transducer region to form a first element of the transducer. The transducer includes an electrically conductive magnetic deposit. The electrically conductive magnetic deposit forms a sidewall on the core. The electrically conductive magnetic deposit forms a second element of the transducer in the transducer region. The second element of the transducer has a planarized surface that is coplanar with a planarized surface of the sidewall.

  • Writer heater for recording heads
    Publication number: 20060285248
    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.

  • Etch-stop layers for patterning block structures for reducing thermal protrusion
    Publication number: 20060102956
    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.
