Dynamically adapting a read channel equalizer

摘要

Provided is a read channel incorporated in a storage device to process signals read from a storage medium. The read channel includes an equalizer equalizing input read signals to produce equalizer output signals. A detector senses an adjusted equalizer output signal to determine an output value comprising data represented by the input read signals. An equalizer adaptor receives the output value from the detector to determine a first error signal used to adjust the equalizer operations. A component adjusts the equalizer output signals being transmitted to the detector, wherein the component is adjusted by a second error signal calculated from the output value from the detector, wherein the first and second error signals are different.
