Abstract:
1. A data recording/reproducing apparatus, comprising: an error correction encoder configured to conduct error correction encoding on input data and generate an ECC sector including error correction encoded data that are divided into predetermined data units; an iterative encoder configured to conduct iterative encoding on the predetermined data units and generate an iterative encoded ECC sector including iterative encoded data units; a distribution unit configured to distribute the iterative encoded data units of at least two of the iterative encoded ECC sectors generated by the iterative encoder and generate interleaved ECC sector data; a recording unit configured to record the interleaved ECC sector data on a recording medium; a reproducing unit configured to reproduce the interleaved ECC sector data from the recording medium; a de-interleaving unit configured to de-interleave the interleaved ECC sector data reproduced by the reproducing unit; an iterative decoder configured to conduct iterative decoding on the de-interleaved ECC sector data output by the de-interleaving unit; and an error correction decoder configured to conduct error correction decoding on the iterative decoded ECC sector data output by the iterative decoder.
