摘要：A method and system for providing an energy assisted magnetic recording(EAMR) disk drive are described. The EAMR disk drive includes a media, a slider having a

trailing face and an air-bearing surface (ABS), at least one distributed feedback (DFB)layer and EAMR transducer(s) on the slider. The DFB laser(s) each includes a plurality ofquantum wells, a laser coupling grating, at least one reflector, and a cavity in the at leastone DFB laser. The DFB laser(s) for providing energy to the media. The EAMRtransducer(s) includes at least one waveguide, a write pole, at least one coil for

energizing the write pole, at least one grating, and may include a near-field transducer.The grating(s) include a coupling grating for coupling the energy from the at least oneDFB laser to the waveguide(s). The waveguide(s) direct the energy from the at least onegrating toward the ABS.
