ABSTRACT:
A data recording/reproducing method and apparatus for correcting data errors on a recording medium even with the use of a conventional ECC. The data recording/reproducing apparatus includes a generation unit that generates predetermined data units by dividing an ECC sector including error correction codes generated by an error correction encoder into prescribed data units and encoding the prescribed units into iterative encoded data units using an iterative encoder so that the predetermined data units may include the iterative-encoded data units, a recording unit, a reproducing unit, an iterative decoder for conducting iterative decoding on the predetermined data units, and an error correction decoder. The apparatus further includes a distribution unit for distributing the predetermined data units generated by the generation unit. The distribution unit distributes the iterative encoded data units using at least two ECC sectors and records the distributed data units on a recording medium.
