Abstract:
1. An energy assisted magnetic recording (EAMR) transducer coupled with a laser for providing energy and having an air-bearing surface (ABS) configured to reside in proximity to a media during use, the EAMR transducer comprising: a waveguide configured to direct the energy from the laser toward the ABS; a near field transducer (NFT) proximate to the ABS, the NFT being optically coupled with the waveguide and for focusing the energy onto a region of the media; a write pole configured to write to the region of the media, the write pole having a magnetic portion and a nonmagnetic liner, the magnetic portion having a plurality of sides and a pole thermal conductivity, the nonmagnetic liner being adjacent to at least the plurality of sides and having a liner thermal conductivity greater than the pole thermal conductivity; and at least one coil for energizing the write pole.
