1. Decoding apparatus for iterative decoding of multidimensionally coded information, comprising:

  • means for performing at least one decoding iteration on multidimensionally coded information;

    means for checking the decoded information after each decoding iteration for errors;

    error detection and correction means for performing error detection and correction on said decoded information; and

    means for causing the decoding iteration means to perform a further decoding iteration if (i) a checking result from the checking means indicates that an error exists in the decoded information and (ii) the number of iterations is less than a predetermined number and for causing the error correction means to perform error correction on the decoded information if (i) a checking result from the checking means indicates that an error exists in said decoded information and (ii) the number of iterations is equal to the predetermined number.
