Abstract
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.

An apparatus comprising:
- a magnetic write head including a near field transducer and a write pole;
- and
- a magnetic recording media including a media lubricant, wherein
- 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, and
- the second portion of the media lubricant that is evaporated removes a contaminant over the near field transducer.
3 more elements
An apparatus comprising:
- a first region of a magnetic recording media;
- and
- a second region of the magnetic recording media that is evaporated in response to heat emitted from a near field transducer on a write head including a write pole, wherein the second region that is evaporated removes contaminants over the near field transducer.
A method comprising:
- heating a first region of a magnetic recording media with a near field transducer on a write head including a write pole, wherein the heating causes a contaminant to form over the near field transducer;
- and
- heating a second region of the magnetic recording media with the near field transducer, wherein
- the second region is evaporated in response to the heating, and
- the second region that is evaporated removes the contaminant over the near field transducer.
