Abstract
A method and system for providing an EAMR transducer is described. The EAMR transducer is coupled with a laser for providing energy and has an ABS that resides near a media during use. The EAMR transducer includes a write pole, coil(s) that energize the pole, a near field transducer (NFT) proximate to the ABS, a waveguide, and a reflector. The write pole has a back gap region and writes to a region of the media. The NFT focuses the energy onto the media. The waveguide directs the energy from the laser toward the NFT at an incident angle with respect to the ABS. A first portion of the energy reflects off of the ABS at a reflected angle. The reflector receives the first portion of the energy from the ABS and reflects a second portion of the energy toward the ABS. The NFT resides between the waveguide and the reflector.
