摘要： A method of generating parity data based on a low-density panty check matrix and an apparatus therefor, the method including: reordering columns of the parity check matrix based on elements in each column having values of one to generate a reordered parity check matrix; determining a cross-point between a diagonal line of a parity matrix part in the parity check matrix and a reordered diagonal line defined by a first entry of an element having a value of one in each column of the reordered parity check matrix; and performing column permutations on the reordered parity check matrix on the basis of positions of elements having a value of one in rows above a horizontal line that passes through the cross-point to generate a triangular matrix, thus reducing the computations required to generate parity data, thereby efficiently obtaining the parity data.

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.
