  • Erasure flagging system and method for errors-and-erasures decoding in storage devices
    Patent number: 8214718
    Abstract: A system and method for erasure flagging for errors-and-erasures decoding in storage devices includes determining a deviation measure between a read/write head position relative to a track of symbols in storage media. A reliability value is determined for the symbols based on the deviation measure. Flagging the symbols with a reliability value below a threshold as erasures is performed. The symbols are decoded using errors-and-erasures decoding in an iterative procedure.
