Abstract
A method of mitigating an effect of track misregistration on read performance in a system comprising an array-reader includes determining an estimated off-track condition, selecting translation coefficients based on the estimated off-track condition, determining updated equalizer coefficients by applying the translation coefficients to native equalizer coefficients, and applying the updated equalizer coefficients to signals received from the array-reader to output a read signal.
