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, the NFT including a disk having an NFT width in a track width direction; a write pole configured to write to the region of the media; a heat spreader thermally coupled with the NFT, a first portion of the heat spreader residing between the NFT and the pole and having a first width in the track direction, a second portion of the heat spreader having a second width in the track width direction, the first portion being between the ABS and the second portion, the second width being greater than the first width; and at least one coil for energizing the write pole.
