摘要
The present invention relates to an error correction coding method and apparatus, an error correction decoding method and apparatus, and a data recording / reproducing apparatus and a storage medium, which divide data into first blocks of a predetermined size, Dividing the data into a plurality of channels and inputting the data into the memory, encoding at least two types of error correction codes in units of second blocks for data input to the memory for each channel, and adding a test parity to generate a third block, The third block is read by adding another offset amount in accordance with the channel, and the data series formed by multiplexing the read data beforehand in units of a predetermined amount is recorded in the storage medium, whereby the interleave processing at the time of recording and the deinterleave processing at the time of reproduction The memory capacity required for the memory card is reduced.
