Abstract
A recording head includes a waveguide core and write pole extending to a media-facing surface of the recording head. A near-field transducer is located between the waveguide core and the write pole. First and second side shields are located on either crosstrack side of the near-field transducer. The first and second shields have edges facing and conformal with first and second tapered sides and a peg of the near-field transducer such that there are respective first and second constant-width gaps therebetween.
