ABSTRACT:
A method of calculating bias compensation values for track seeking, including: setting a reference track, and search tracks disposed between the reference track and an innermost track and between the reference track and an outermost track; calculating bias compensation values usable for compensating for biases operating on a magnetic head while moving the magnetic head a direction from the reference track to one of the outermost track and to the innermost track, and then in another direction from the reference track to other of the one of the innermost track and the outermost track; and making bias compensation curves according to head moving distances using the calculated bias compensation values.
