Abstract
The invention is generally directed to a disk drive head resetting system. The system has a slider with a disk drive head associated therewith. The disk drive head may be on the slider and affixed thereto. A heater is also associated with a slider and spaced apart from the disk drive head. A controller is communicatively coupled to the heater and to the head to transfer a first control signal to the heater and a second control signal to the disk drive head at substantially the same time. The first control signal may be used to generate heat past a blocking temperature of the head to substantially free a magnetic orientation of the head. While the first control signal is being transferred to the heater, a second control signal is transferred to the disk drive head to align a magnetic orientation of the head to a desired magnetic orientation.
