A decoding system includes a decoder, a first module and a second module. The decoder is configured to receive data read from an optical storage medium and perform a first decoding iteration and a second decoding iteration to decode the data. The first decoding iteration includes generating a resultant matrix. The first module is configured to, based on first decoding statuses of multiple bytes in the resultant matrix, determine second decoding statuses of bytes proximate to failed bytes of a feedback matrix. The feedback matrix is generated based on the resultant matrix. The first module is configured to mark selected ones of the failed bytes as erasures based on the second decoding statuses. The second module is configured to correct one or more of the bytes marked as erasures during the second decoding iteration. |
