Abstract: A transducer comprises a slider and a laser arrangement. The laser arrangement is configured to heat a region of a magnetic medium in proximity to the slider and produce modulated laser light to cause heat-induced modulation of the slider. The laser arrangement is configured to couple laser light at a power that reduces a coercivity of magnetic material at the region for writing data to or erasing data at the region, and couple modulated laser light to cause heat-induced modulation of the slider at a power lower than the power for writing data to or erasing data at the magnetic medium.

Abstract: An apparatus comprises a laser diode configured to generate light during a write operation. A slider comprises a near-field transducer (NFT) and an optical waveguide. The slider is configured for heat-assisted magnetic recording and to communicate the light to the NFT via the waveguide. A writer heater of the slider is configured to receive power during the write operation. A thermal sensor is situated at or near an air bearing surface of the slider. The thermal sensor is configured to produce a sensor signal in response to sensing back-heating from the medium while the NFT generates heat during a write operation. Circuitry, coupled to the thermal sensor, is configured to compare the sensor signal to a threshold and generate an output signal indicative of degradation of NFT performance in response to the sensor signal exceeding the threshold.
