    Abstract: A sensor supported by a head transducer has a temperature coefficient of resistance (TCR) and a sensor resistance. The sensor operates at a temperature above ambient and is responsive to changes in sensor-medium spacing. Conductive contacts connected to the sensor have a contact resistance and a cross-sectional area adjacent to the sensor larger than that of the sensor, such that the contact resistance is small relative to the sensor resistance and negligibly contributes to a signal generated by the sensor. A multiplicity of head transducers each support a TCR sensor and a power source can supply bias power to each sensor of each head to maintain each sensor at a fixed temperature above an ambient temperature in the presence of heat transfer changes impacting the sensors. A TCR sensor of a head transducer can include a track-oriented TCR sensor wire for sensing one or both of asperities of the medium.

    Abstract: An apparatus comprising a writer, a reader, and a sensor configured to at least sense thermal asperities of a magnetic storage medium. The apparatus includes a writer heater configured to thermally actuate the writer, a reader heater configured to thermally actuate the reader, and a sensor heater configured to thermally actuate the sensor. The thermally actuated sensor is configured to detect thermal asperities arising from the magnetic storage medium during a topographical survey of the medium. The sensor heater is configured to be rendered inoperable subsequent to the survey in response to receiving a predetermined signal while the writer and the reader heaters remain operable.
