Abstract: A recording head has a waveguide that delivers optical energy from an energy source and a write pole extending to a media-facing surface of the recording head. The recording head also has a near-field transducer coupled to receive the optical energy from the waveguide and emit surface plasmons from the media-facing surface towards a recording medium while the write pole applies a magnetic field to the recording medium. The near-field transducer has an extended portion that, as-manufactured, protrudes beyond the media-facing surface by a first distance.

Abstract: A method involves forming a recording head that comprises a waveguide, a write pole, and a near-field transducer proximate the write pole. The near-field transducer has an extended portion extending towards a surface of the recording head and operable to direct plasmons to a recording medium. The surface of the recording head is lapped to form a lapped surface. A resist or hardmask is patterned on the lapped surface in a region that encompasses the extended portion. The lapped surface is etched with the resist or hardmask pattern to form a media-facing surface such that the extended portion protrudes beyond the media-facing surface by a first distance, and the resist or hardmask is removed.

Abstract: The present disclosure relates to a recording head that includes a write pole extending to a media-facing surface of the recording head; a near-field transducer extending to a media-facing surface of the recording head; a trailing return pole positioned between the write pole and the trailing edge; and a recessed portion that is recessed relative to the media-facing surface by a distance when no power is applied to the recording head. The trailing return pole is located in the recessed portion. The present disclosure also includes relates methods of making and detecting contact between a recording head and recording medium.
