Abstract:
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 position error signal (PES).
