Abstract
A method and system for providing an energy assisted magnetic recording (EAMR) transducer coupled with a laser are described. The laser provides energy. The EAMR transducer has an air-bearing surface (ABS) configured to reside in proximity to a media during use. The EAMR transducer includes a near field transducer (NFT) proximate to the ABS for focusing the energy onto the region of the media. The method and system include providing a heat sink having a bottom thermally coupled with the NFT and a top surface at an angle with respect to the ABS. The angle is greater than zero and less than ninety degrees. The method and system also include providing a write pole and at least one coil. The write pole is configured to write to a region of the media. The write pole has a bottom surface thermally coupled with the top surface of the heat sink. The at least one coil is for energizing
