  • 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.

  • Patent number: 7123447
    Abstract: To reduce thermal pole-tip protrusion and recession, a magnetic head includes a multi-material basecoat. The magnetic head has an air bearing surface and a back surface opposite the air bearing surface. The magnetic head includes a substrate and the basecoat positioned upon the substrate. The basecoat has a first portion and a second portion wherein a Young's modulus of the first portion is less than a Young's modulus of the second portion. A data transducer is positioned upon the basecoat adjacent the air bearing surface.

  • Publication number: 20060193081
    Abstract: A transducing device includes a writer having a pole tip region and a heater circuit. The heater circuit has a heating portion and a heater current return path. The heating portion has at least two branches positioned with respect to the writer so that current flowing through the at least two branches heat the writer. The heater current return path is electrically connected to the at least two branches of the heating portion near the pole tip region and includes an electrically conductive portion of the writer.

  • Publication number: 20050057841
    Abstract: A head with a heating element and control regime therefor is disclosed. In embodiments described, the control regime or controller energizes the heater or heating element to provide intermittent heating between read or write operations to optimize transducer temperature and operating characteristics or parameters of a data storage device. In particular, in one embodiment described, the controller provides a low amplitude signal or current to provide low grade thermal heating. In another embodiment, the controller provides a high amplitude signal or current to preheat the transducer portion for write operations.

  • Publication number: 20050036238
    Abstract: A microelectronic device includes a transducer. An overcoat layer is disposed on a transducer surface. A plurality of electrical contact pads are disposed on the overcoat layer. First and second studs that pass through the overcoat layer to connect the transducer to the electrical contact pads. The first and second studs are separated from one another by a reduced spacing distance that is free of trenching.
