Abstract:
A near-field transducer includes an enlarged region having a top side adjacent to a magnetic pole, a base side opposite the top side, and a circumference that extends from proximal to a media-facing surface to distal to a media-facing surface. The near-field transducer includes a peg region in contact with a region of the bas side of the enlarged region, the peg region extending from the enlarged region towards the media-facing surface. The near-field transducer also includes a heat sink region having a contact side, a base side, and a circumference that extends from proximal to the media-facing surface to distal from the media-facing surface. The contact side of the heat sink region is in thermal contact with both the peg region and at least a region of the base side of the enlarged region.
