Abstract: A method and apparatus for detecting and correcting errors in a magnetic recording channel of a mass storage system that combines a Soft Output Viterbi Algorithm SOVA, which has the capability of detecting the reliability of a discrete, equalized signal, and a post processor, which has the capability of detecting specific error events in said discrete, equalized signal, so as to correct error events and to generate an output bit stream.
