摘要:
A media defect compensation system and method may decouple effects of asymmetry from baseline error compensation computations. In some embodiments, a switching mechanism passes a baseline error signal into a baseline loop when a determination is made that a baseline error signal is not affected by asymmetry, and otherwise freezes the baseline loop when asymmetry may influence baseline error calculations.
