ABSTRACT:
The invention is a servo compensation method and system for use in a disk storage system. The disk storage system experiences error that causes a head to become mis-aligned with the disk. The error comprises run-out error and other servo position errors. During follow mode, a digital filter processes a position error signal to generate a compensation signal. The position error signal is comprised of components representative of the run-out error and the other servo position errors. The compensation signal is comprised of components that cause the servo positioning system to compensate for the run-out error and the other servo position errors. The digital filter also operates as an oscillator that provides an oscillating signal the spin frequency of the disk during seek mode.
