Abstract
A recording head has a near-field transducer at a media-facing surface of the recording head and a write pole on a first side of the near field transducer. A first coil induces a first flux in the write pole. The recording head includes a shield on a second side of the near-field transducer that faces away from the first side. A second coil is proximate the shield and induces a second flux in the shield that controls a field angle of the first flux.
