摘要:
A near-field transducer has an enlarged portion with a peg extending towards a media-facing surface. Two reflectors are located co-planar with near-field transducer and located on either side of the near-field transducer in a crosstrack direction. The two reflectors are separated by a gap proximate the peg of the near-field transducer. The two reflectors each include a first edge at the media facing surface and a second edge at an acute angle to the media-facing surface. The second edge faces the near-field transducer. The two reflectors concentrate the light on the peg of the near-field transducer.
