Abstract:
1. A heat assisted magnetic recording (HAMR) write 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 HAMR transducer comprising: a main pole configured to write to a region of the media, the main pole being recessed from the ABS by a first distance, the main pole including a bottom surface and a top surface opposite to the bottom surface, the bottom surface having a sloped portion that is sloped at an angle from perpendicular to the ABS, the angle being greater than zero degrees and less than ninety degrees; at least one additional pole adjacent to the main pole in a down track direction, the additional pole being recessed from the ABS by a second distance greater than the first distance; a waveguide optically coupled with the laser and directing a portion of the energy toward the ABS at an acute angle from the ABS, a portion of the waveguide residing between the at least one additional pole and the ABS, the bottom surface of the main pole being closer to the waveguide than the top surface of the main pole is; and at least one coil for energizing the main pole.
