    Abstract: An apparatus includes a write pole magnetically coupled to write coils that generate a first magnetic field during a switching event. The apparatus includes a shield at a media-facing surface and proximate the write pole. A conductive element is disposed proximate the shield and configured to generate a second magnetic field opposite to the first magnetic field during the switching event. A selected one of the write coils is located adjacent the shield separate from others of the write coils.

    Abstract: In accordance with one embodiment, an apparatus can be configured that includes a main pole layer of magnetic material; a second layer of magnetic material; a first gap layer of non-magnetic material disposed between the main pole layer and the second layer of magnetic material; a second gap layer of non-magnetic material disposed between the main pole layer and the second layer of magnetic material; and wherein the second gap layer of non-magnetic material is disposed directly adjacent to the second layer of magnetic material. In accordance with one embodiment, this allows the gap to serve as a non-magnetic seed for the second layer of magnetic material. In accordance with one embodiment, this allows the gap to serve as a non-magnetic seed for the second layer of magnetic material. In accordance with one embodiment, a method of manufacturing such a device may also be utilized.

    Abstract: A recording head includes a magnetic write transducer proximate a near-field transducer. The magnetic write transduce includes a yoke extending in a direction normal to a media-facing surface and a having an edge facing and recessed from the media-facing surface. A write pole extends beyond the first end of the yoke towards the media-facing surface and overlaps a first surface of the yoke that faces the near-field transducer. The write pole has a stepped edge facing away from the media-facing surface. Two or more coil turns are stacked relative to one another in a down-track direction. The two or more coils face a second surface of the yoke that is opposed to the first surface.
