  • Writer core incorporating thermal sensor having a temperature coefficient of resistance
    Patent number: 9679598
    Abstract: A writer core of a transducer is configured to interact with a magnetic recording medium and comprises an upper core and a lower core. At least one of the upper and lower cores comprises a return pole having a return shield. The apparatus also comprises a writer pole between the upper and lower cores, and a writer gap defined between the writer pole and the return shield. The apparatus further comprises a sensor element within one of the upper and lower cores that includes the writer gap. The sensor element has a temperature coefficient of resistance and is configured to sense for a change in temperature indicative of one or both of a change in spacing and contact between the transducer and the magnetic recording medium.
