Abstract: A near-field transducer includes an enlarged portion and a peg protruding from a first edge. The enlarged portion has a second edge facing away from the first edge. The near-field transducer includes a heat sink disposed on the enlarged portion and with an outline shape that matches that of the enlarged portion. The heat sink is disposed at a first separation distance from the first edge of the enlarged portion and a second, greater, separation distance from the second edge of the enlarged portion. The first separation distance is greater than the second separation distance.

Abstract: An apparatus includes a waveguide, a magnetic pole, and a near-field transducer. The near field transducer is positioned at or near a media-facing surface. The near-field transducer is operatively coupled to the waveguide. The near-field transducer includes an enlarged region. The near-field transducer also includes a peg region extending from the enlarged region towards the media-facing surface. The peg region is separated from the magnetic pole. The near-field transducer also includes a structure positioned between the magnetic pole and the peg region. The structure is separated from the peg region by a gap. The structure extends from the enlarged region towards the media-facing surface. The structure is configured to extend generation of surface plasmons toward the magnetic pole.

Abstract: An apparatus comprises a writer, a near-field transducer (NFT), a channel waveguide proximate the NFT, a dielectric layer between the NFT and waveguide, and a plurality of heat sinks. A first heat sink comprises a gap and contacts the NFT and the writer. A second heat sink extends across the gap of the first heat sink and between the NFT and a heat reservoir component, such as a return pole of the writer. The channel waveguide may contact the second heat sink, such as by encompassing a peripheral portion of the second heat sink. The second heat sink may have at least an outer surface comprising a plasmonic material, and may be configured to enhance plasmonic excitation of the NFT.
