With two consecutive product-coded ECC blocks, EB1 and EB2, as a set, the rth row of first ECB block EB1 is followed by the rth row of second ECC block EB2 in such a way that the first row of first ECC block EB1 is followed by the first row of second ECB block EB2, which is followed by the second row of first ECC block ECB1, which is followed by the second row of second ECC block EB2, and so on, to interleave data on a row basis. That is, data of two ECC blocks, EB1 and EB2, is allocated alternately on a row basis. This allocation method allows an error to be distributed after reproduction even when a serious burst error extending 18 rows occurs in an ECC block.
