Various systems and methods for error reduction in a digital information system are disclosed herein. As one example, a digital storage system is provided that includes a soft output Viterbi algorithm channel detector operable to receive an encoded data set, and to provide a hard and a soft output representing the encoded data set. The hard and the soft output from the soft output Viterbi algorithm channel detector are provided to a single parity row decoder that provides another hard output that is an error reduced representation of the encoded data set. The encoded data set is additionally provided from the buffer to another channel detector via a delay element. The hard output from the single parity row decoder and the time shifted encoded data set are provided to coincident with each other to another channel detector.
