    Abstract: Disclosed are plasmonic near-field transducers that are useful in heat-assisted magnetic recording. The disclosed plasmonic near-field transducers have an enlarged region and a flared region. In some embodiments the disclosed plasmonic near-field transducer can also include a peg region. The flared region can act as a heat sink and can lower the thermal resistance of the peg region of the near-field transducer, thus reducing its temperature. Also disclosed are methods that include delivering light to a magnetic transducer region via a waveguide, receiving the light at a plasmonic near-field transducer having an output end and disposed in proximity to the magnetic transducer region, and delivering a surface plasmon-enhanced near-field radiation pattern proximate the output end of the plasmonic transducer in response to receiving the light,

    Abstract: An apparatus includes a slider structure having a waveguide and a cavity configured to align a laser to the waveguide. The cavity includes a plurality of solder bumps on a bottom of the cavity configured to electrically and thermally couple the laser to the slider. At least one mechanical stopper is disposed in the cavity to facilitate vertical alignment between an output of the laser and an input of the waveguide. At least one solder bump is disposed on the mechanical stopper to facilitate lateral alignment between the output of the laser and the input of the waveguide in response to a reflow of the solder bumps.

    Abstract: While a heat-assisted, magnetic recording media is not being written to, heat applied from a write head to the recording media to facilitate writing to the recording media is removed. Power is applied to a write coil of the write head to control spacing between the write head and the recording media when the recording media is not being written to.

    Abstract: An apparatus comprises a slider configured to facilitate heat assisted magnetic recording. The slider comprises a plurality of bond pads including a first electrical bond pad, a second electrical bond pad, and a ground pad. A laser diode comprises an anode coupled to the first electrical bond pad and a cathode coupled to the second electrical bond pad. The laser diode is operable in a non-lasing state and a lasing state. A heater is coupled between the ground pad and at least one of the anode and cathode of the laser diode. The heater is configured to generate heat for heating the laser diode during the non-lasing state and the lasing state.
