Abstract:
An apparatus includes a waveguide, a magnetic pole, and a near-field transducer. The near field transducer is positioned at or near a media-facing surface. The near-field transducer is operatively coupled to the waveguide. The near-field transducer includes an enlarged region. The near-field transducer also includes a peg region extending from the enlarged region towards the media-facing surface. The peg region is separated from the magnetic pole. The near-field transducer also includes a structure positioned between the magnetic pole and the peg region. The structure is separated from the peg region by a gap. The structure extends from the enlarged region towards the media-facing surface. The structure is configured to extend generation of surface plasmons toward the magnetic pole.
