Abstract
A magnetic device includes first and second electrodes and a sensor stack connected to the first and second electrodes proximate a sensing surface of the magnetic sensor. A resistive element is connected to the first and second electrodes in parallel or in series with the sensor stack and adjacent the sensing surface. In some embodiments, the resistive element is configured to generate signals related to changes in its resistance. A controller to respond to the resistive element signals can also be included.
