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 of quantum wells, a laser coupling grating, at least one reflector, and a cavity in the at least one DFB laser. The DFB laser(s) for providing energy to the media. The EAMR transducer(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 one DFB laser to the waveguide(s). The waveguide(s) direct the energy from the at least one grating toward the ABS.

摘要： A method for providing energy assisted magnetic recording (EAMR) heads are described. The method and system include providing a substrate, at least one EAMR transducer, an overcoat layer and at least one laser. The substrate has a leading edge and a substrate trailing edge. The EAMR transducer(s) reside in a device layer and on the substrate trailing edge. The overcoat layer includes a plurality of contacts. The device layer is between the overcoat layer and the substrate trailing edge. The laser(s) provide energy to the EAMR transducer. The overcoat layer is between the substrate trailing edge and the laser(s). The laser(s) are electrically coupled to at least a first portion of the contacts. The contacts provide thermal connection through the overcoat layer and through the device layer to the substrate. At least a second portion of the contacts is electrically insulated from the substrate.

摘要： A magnetic recording media is disclosed. The media comprises a substrate, a recording layer disposed over the substrate, and a metallic layer disposed between the recording layer and the substrate. The recording layer is configured to receive an electromagnetic radiation, absorb a first portion of the electromagnetic radiation, and transmit a second portion of the electromagnetic radiation. The metallic layer comprises a non-magnetic metal and configured to reflect at least some of the second portion of the electromagnetic radiation towards the recording layer.
