Abstract
Technologies are described herein for detecting an external magnetic field affecting a magnetic storage device through use of the read/write heads of the device. The magneto-resistive resistance ('MRR') associated with a pair of read/write heads oriented to read and write opposite recording surfaces of the storage medium. If the change in the MRR associated with the first read/write head is in an inverse direction to the change in MRR associated with the second read/write head and the change in the MRR of either read/write head exceeds a threshold, then all operations of the storage device are halted and the read/write heads are parked.
