Abstract
A recording head includes a near-field transducer proximate a media-facing surface of the recording head and a waveguide that overlaps and delivers light to the near-field transducer. The recording head includes subwavelength-sized focusing mirror comprising first and second reflectors disposed on cross track sides of the near-field transducer. Each of the first and second reflectors is spaced apart from the media-facing surface by a distance, D, measured along an axis normal to the media-facing surface.
