A method is disclosed which decreases the amount of error correction code data required to detect and correct errors in digital data while still maintaining a specified ability to correct errors in large groups of contiguous data. The present invention accomplishes this by placing distance either in space or in time between symbols grouped mathematically for error correction code calculations. An error affecting contiguous symbols, like scratches or other defects in digital storage media, or certain types of interference in either wired or wireless digital communications, would affect many error correction code groups, but would only affect one symbol from each group. The error can easily be corrected using only a one dimensional error correction code, removing the need for a two dimensional product error correction code and the additional data overhead that the column ECC data necessarily adds to the block.
