Abstract
A method and apparatus for protecting a thin film sensor such as a magnetoresistive head from damaging electrical transients, such as electrostatic discharge. A thin film sensor assembly includes a thin film sensor in electrical contact with a first and a second electrical contact. A shunting structure is deposited between and in electrical communication with the first and second electrical contacts such that the shunting structure as deposited is a high resistance path between the first and second electrical contacts and does not electrically short the first and second electrical contacts. Heat treating the shunting structure then forms a low resistance path between the first and second electrical contacts to provide protection of the sensor from electrostatic discharge.
