Near-field transducer having enlarged portion matching outline shape of heat sink

A write head, comprising:

• a write pole extending towards a media-facing surface that faces a recording medium;
• and
• a near-field transducer, comprising:
• an enlarged portion and a peg protruding from a first edge of the enlarged portion at the media-facing surface, the enlarged portion comprising a second edge facing away from the media-facing surface;
• and
• a heat sink disposed on the enlarged portion and having an outline shape that matches that of the enlarged portion, the heat sink disposed at a first separation distance from the first edge of the enlarged portion and a second separation distance from the second edge of the enlarged portion, the first separation distance being greater than the second separation distance.
