摘要： An apparatus, method, and an optical storage medium to generate an error correction block include a data block generation unit processing digital data on a byte-by-byte basis and arranging the processed digital data from 0th to (N−1)th columns and from 0th to (M−1)th rows to form (M×N) data blocks. A matrix block generation unit arranges the (M×N) data blocks in K rows according to a data transmission sequence to form a matrix block. A first codeword generation unit adds a first error correction check word of 2×K bytes to each of N columns to form a first codeword of ((K×M)+2×K) bytes. A second codeword generation unit adds a second error correction check word of P bytes to each of ((K×M)+2×K) rows to form a second codeword of (N+P) bytes.

摘要： An optical recording medium, a data recording or reproducing apparatus, and a data recording or reproducing method used by the data recording or reproducing apparatus. In a method of recording data on an optical disc, each of a plurality of error correction code (ECC) blocks is divided into a plurality of partitions. Next, data from the partitions is interleaved so that each of the ECC blocks is alternately and equally selected to generate a recording block. The generated recording block is modulated and recorded on an optical disc. As a result, the optical recording medium, the data recording apparatus, and the data recording method used by the apparatus are compatible with the format of a conventional digital versatile disc (DVD) and have higher error correction rates. In a reproducing method, the recording block is deinterleaved.

摘要： A decoding method and an apparatus operate by performing error correction on code words of an error correcting code block in one direction selected from a row direction and a column direction, indicating in error flags the remaining code words except at least some code words from code words having uncorrectable errors, and performing error correction on code words in the other direction based on the error flags. Accordingly, errors that have been conventionally considered as being uncorrectable may now be corrected.
