摘要： A bias signal is applied to a resistive thermal sensor located proximate a magnetic media reading surface of a magnetic sensor. The bias signal is modulated between first and second bias levels. First and second resistances of the resistive thermal sensor corresponding to the first and second bias levels are measured. Based a difference between the first and second resistances caused by in increase in thermal conductivity between the magnetic sensor and a medium as the magnetic head gets closer to the medium, at least one of a spacing and a contact between the magnetic sensor and the medium are determined.

摘要： A slider includes a slider body having an air bearing surface, a first contact finger, and a transducing head. The first contact finger extends from the slider body and has a contact surface area of between about 2 square microns to about 20 square microns. The transducing head is supported by the slider body near the first contact finger and extends from the air bearing surface by a distance less than that of the first contact finger.
