Abstract:
A near-field transducer includes an enlarged transducer portion of plasmonic material extending from an input end to an output end, a surface of the transducer portion including a trench running between two raised portions of the plasmonic material, the trench extending at least partially from the input end to the output end. A peg of the plasmonic material is disposed on the output end of the transducer portion and extends from the output end toward the air bearing surface of a heat assisted magnetic recording slider.
