Abstract
A method for recording data onto a disc-shaped recording medium having a sector construction such as an optical disc by dividing input data into predetermined lengths, respectively, two-dimensionally arranging the divided data, generating and adding error correction codes to the two-dimensionally arranged data by a predetermined series to thereby form n encoded blocks; changing the data arrangement among the n encoded blocks; and distributing and recording the changed data to each sector on the disc-shaped recording medium.
