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.
