Abstract
A disk drive is disclosed which has a facility to perform a pinning reset operation on a GMR read element included in a head if a read retry operation fails to achieve recovery from a read error. When a bias and write currents are supplied to the head, a CPU of the disk drive determines an optimum bias and write currents on the basis of a temperature measured value of the GMR read element.
