摘要： In an example, a method comprises aligning a central axis of a paddle portion on a write pole circuit to be substantially perpendicular to an adjacent magnetic surface, and bending a central axis of an extended tip portion relative to the central axis of the paddle portion. In another example, a transducer head comprises a write pole circuit having a paddle portion with a central axis, and an extended tip portion with a central axis, the central axis of the extended tip portion angled from the central axis of the paddle portion. In another example, a magnetic circuit comprises a write pole circuit having a paddle portion and an extended tip portion, the extended tip portion bending away from a central axis of the paddle portion, and a coil wrapping around the extended tip portion.

摘要： 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.

摘要： 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.

摘要： A recording head has a near-field transducer at a media-facing surface of the recording head and a write pole on a first side of the near field transducer. A first coil induces a first flux in the write pole. The recording head includes a shield on a second side of the near-field transducer that faces away from the first side. A second coil is proximate the shield and induces a second flux in the shield that controls a field angle of the first flux.
