ABSTRACT:
A scheme in which a first decoder provides first decoding of a signal read from a disk. A second decoder, coupled to an output of the first decoder, combines with the first decoder to provide iterative decoding to recover data stored on the disk when in an iterative mode of operation. However, when in a non-iterative mode of operation, the output of the first decoder is coupled to an error correction code module to apply error correction code (ECC) to the output of the first decoder to recover data stored on the disk by non-iterative decoding.
