ABSTRACT:
A disc recording medium is provided for enhancing a capability of correcting a burst error caused by small dust left on the surface of a disc substrate. The data of two-dimensionally arrayed ECC blocks consisting of 172 words.times.192 rows contains the PI parity and the PO parity added in the two error-correcting systems. The PI parity is intended for error correction for data arranged to go down by one row with advance of one word in the direction of a bit stream. The PI parity is intended for going back to the first row when the data being interleaved exceeds 192 rows. The PO parity is intended for error correction for data arranged to interleave the data perpendicularly to the bit stream.
