Beschreibung
Zusammenfassung:	The present invention relates to 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 (39), having the capability of detecting the reliability of a discrete, equalized signal (38), and a post processor (37), having the capability of detecting specific error events in said discrete, equalized signal (38), so as to correct said error events and to generate an output bit stream (48).
