    Abstract: 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).

    Abstract translation: 本发明涉及一种用于检测并在一个大容量存储系统的磁记录信道校正误差的方法和装置,确实结合了一个软输出维特比算法SOVA(39),其具有检测离散的可靠性的能力,均衡信号 (38),以及具有在所述离散检测特定的错误事件的能力的后处理器(37),均衡后的信号(38),以便校正所述错误事件并在输出位流(48),以产生。
