Abstract
A method and system for providing an energy assisted magnetic recording (EAMR) transducer coupled with a laser are described. The EAMR transducer has an air-bearing surface (ABS) configured to reside in proximity to a media during use. The method and system include providing at least one waveguide, at least one write pole, and at least one coil. The waveguide(s) are for directing the energy from the laser toward the ABS. The write pole(s) each include a write pole tip, a yoke, a back pedestal and a return pole. The write pole tip is coupled to the back pedestal through the yoke. The back pedestal has at least one aperture therein. The aperture(s) are configured to allow the energy from the laser to pass therethrough. The coil(s) are for energizing the at least one write pole.
