Latest Patents

Andrea holds a patent for "Head-medium contact detection using an oscillating electromagnetic force." This apparatus comprises circuitry designed to apply an AC signal to either a slider of a recording head or a magnetic recording medium. The applied AC signal induces oscillation in the electrostatic force and clearance between the slider and the medium. A thermal sensor generates a signal in response to temperature changes caused by this oscillating clearance. The detector is configured to identify changes in head-medium spacing and contact using specific harmonics of the thermal sensor signal. This innovation is crucial for improving the reliability and performance of data storage devices.
