摘要:
Multiple signals are read, respectively, from multiple different cross-track positions of a track of a magnetic medium. Weighting coefficients for each of the multiple signals are determined. The weighting coefficients are applied to the respective signals to form weighted signals. The weighted signals are combined and the combined signal is used to recover data stored in the track.
