Abstract
A magnetic write apparatus includes a pole and a near field transducer. The pole extends in a yoke direction from a media facing surface where the yoke direction extends perpendicular to the media facing surface. The near field transducer includes a near field transducer cap and a near field transducer nose. The near field transducer nose is separated from the pole by the near field transducer cap and a dielectric gap and the near field transducer nose comprises a bevel surface that forms a bevel angle with a plane extending in the yoke direction.
