ABSTRACT:
Weight factors corresponding to plural areas into which a disk is concentrically divided, respectively, are previously stored, and an amount of eccentricity control is calculated using the previously-stored weight factors during settling operation. Further, when an impact larger than a predetermined value is applied, calculation of weight factors is stopped. Thereby, the seek time can be shortened, and positioning of the head can be stabilized.
