Abstract: A recording head comprises a write pole extending to an air-bearing surface. A near-field transducer is positioned proximate a first side of the write pole in a down-track direction. A heatsink structure is proximate the near-field transducer and positioned between the near-field transducer and the write pole. The heatsink structure extends beyond the near-field transducer in a cross-track direction and extends in a direction normal to the air-bearing surface.

Abstract: A recording head has a magnetic write transducer proximate a side of a plasmonic gap waveguide. The magnetic write transducer has a first write pole section that tapers in a crosstrack direction and downtrack direction to form a tapered tip. The first write pole section includes a high-moment, seed layer on one side. A second write pole section is coupled to the first write pole section. The second write pole section extends a second distance away from the media-facing surface less than that of the first write pole section. A tip of the second write pole section is tapered in the crosstrack and downtrack directions.
