Abstract:
1. A method of recording data on an optical disc, the method comprising: encoding input data with an error correction code (ECC) to generate ECC encoded data in a plurality of ECC blocks, each ECC block having a predetermined size of rows and columns; dividing each of the ECC blocks of the ECC encoded data further in row and column directions to form a plurality of partitions, each partition having a predetermined unit in row and column directions; interleaving data from the plurality of the partitions by alternately extracting data from the partitions of each of the ECC blocks so that partitions from each of the ECC blocks are alternately selected such that progression through the partitions of each ECC block occurs diagonally to generate a first recording block; modulating the first recording block; and recording the modulated first recording block on the optical disc, wherein the dividing of the ECC blocks comprises dividing each of the ECC blocks in a column direction by a predetermined number of bytes into object blocks; and dividing each of the object blocks in row and column directions by the predetermined number of bytes to generate the plurality of partitions such that each of the object blocks has a same number of units in both the row direction and the column direction.
