摘要: Provided herein is a magnetic write head including a near field transducer and a magnetic recording media including a media lubricant. The media lubricant includes a first portion and a second portion. The second portion of the media lubricant is evaporated in response to heat emitted from the near field transducer. The second portion of the media lubricant that is evaporated removes a contaminant over the near field transducer.

摘要: 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.
