Patent ID: 8599657

Claim:
A method for providing an energy assisted magnetic recording (EAMR) disk drive including a media and a slider having a trailing face and an air-bearing surface (ABS), the method comprising: fabricating at least one EAMR transducer on the slider, the at least one EAMR transducer including at least one waveguide, a write pole, at least one coil for energizing the write pole, least one grating including a coupling grating and a first mirror; and bonding at least one distributed feedback (DFB) laser to the slider, the at least one EAMR transducer residing between the at least one DFB laser and the slider, the at least one DFB laser including a plurality of quantum wells, a second mirror, a laser coupling grating, at least one reflector, and a cavity in the at least one DFB laser, the plurality of quantum wells residing between the second mirror and the cavity, the at least one DFB laser for providing energy to the media, the coupling grating for coupling the energy from the at least one DFB laser to the at least one waveguide, the at least one waveguide directing the energy from the coupling grating toward the ABS and residing between the first mirror and the cavity.
