REPEATED RUNOUT ERROR COMPENSATION USING ITERATIVE FEEDBACK

Various embodiments of the present invention are generally directed to adaptively determining an updated repeated runout (RRO) correction value to correct for RRO error in the placement of a servo seam, by iteratively combining a weighted initially estimated RRO correction value for the seam with a...
