Abstract
A recording head has a write pole with a pole tip extending to a media-facing surface of the recording head. A peg coupler is located on a substrate-parallel surface of the pole tip and extending to the media facing surface. A near-field transducer is proximate the media-facing surface and includes a plate-like, enlarged part with a peg extending from the enlarged part towards the media-facing surface. The peg separated is separated in a downtrack direction from the peg coupler by a coupling gap. The enlarged part has a coupling surface facing the write pole, and includes an inlay on or near the coupling surface and spaced away from the peg. The inlay extends at least partially through a thickness of the enlarged part in the downtrack direction and extends between opposing crosstrack edges of the enlarged part.
