Abstract:
A recording head has a near-field transducer proximate a media facing surface of the read/write head. A waveguide overlaps and delivers light to the near-field transducer. A subwavelength focusing mirror is at an end of the waveguide proximate the media-facing surface. The subwavelength focusing mirror recycles a residual transverse field for excitation of the near-field transducer.
