Abstract
A near-field transducer includes first and second stacked base portions having a common outline shape. The second base portion is proximate alight delivery structure. A peg extends from the first base portion towards a media-facing surface. The peg includes a material that is more thermally robust than a plasmonic material of the base portion. The peg has a peg thickness that is less than a thickness of the first base portion. The first base portion has a first recess proximate the peg. The first recess separates the first base portion from the media-facing surface and exposes at least a top side of the peg.
