Near-field transducer with stacked features that reduce emission of polarization-rotated light

摘要

A recording head has a near-field transducer overlapping a core near a media-facing surface of the recording head. The near-field transducer has an enlarged portion formed of a plasmonic material and a peg extending from the enlarged portion. The enlarged portion includes a stacked feature that reduces the emission of a polarization rotated portion of light to a recording medium.
