Abstract
A servo system includes multiple interpolators operable to interpolate equalized data for multiple signal paths in a two dimensional magnetic recording system to yield interpolated signals at different phases, scaling circuits operable to scale the interpolated signals by adaptive scaling factors, a signal combining circuit operable to combine the scaled signals, a phase tracking circuit operable to select one of the phases of the combined signal, and an error gradient circuit operable to adapt the adaptive scaling factors.
