Abstract
Apparatus, and an associated method, protects against damage to a magnetoresistive sensor of a disk drive assembly, or other magnetic storage device, responsive to a thermal asperity event. Detection is made of the resistance of the magnetoresistive sensor. If the resistance increases, indicative of a temperature increase occurring as a result of a thermal asperity event, a full-sense current, or current of other appropriate magnitude is applied to the sensor, thereby to prevent alteration by the magnetic field of portions of the magnetoresistive sensor.
