Abstract

A burst error-correcting capability is largely improved. At least the even-number row and at least the odd-number row of the data block which is a set of data sectors are separated. An outer parity is created for each column and an inner parity is created for each row. Then, the outer parity is scattered with respect to each of the sectors of the data block to be interleaved.

         2 . A data recording medium which is recorded information by arranging error correction code (ECC) blocks comprising: 
 a plurality of sectors configured to include information;    a first PO creation block corresponding to one of the ECC blocks, being configured by rows in the plurality of sectors; and    a second PO creation block corresponding to an other one of the ECC blocks, being configured by rows in the plurality of sectors, a first PO created into the first PO creation block; and    a second PO created into the second PO creation block, wherein the each row of the first PO is disposed immediately in front of the row, except rows of the second PO, in the second creation block.
