ABSTRACT:
An offset correcting method corrects an offset of a position signal generating circuit which generates a position signal indicative of a position of a magnetic head on a magnetic disk based on servo signal read from the magnetic disk in a magnetic disk unit. The offset correcting method includes the steps of measuring an offset value of the position signal generating circuit, storing the measured offset value in a storing part, and correcting an output value of the position signal generating circuit based on the offset value which is read from the storing part.
