PURPOSE:To prevent the reduction in the error correction capability by setting the interleave interval of an error correction code series longer partially to evade any word of P and Q series with respect to a prescribed object work from being duplicated in the recording direction. CONSTITUTION:The interleave interval of the error correction code series is set longer partially so as to evade the duplication in the recording direction as to words W0-W7 of the P and Q series with respect to the optional object word. Thus, even when the interleave interval is taken sufficiently large due to a small block size, the same frame except the object word is avoided as to each word of each error correction code system with respect to an optional object word. Thus, the reduction in the error correction capability is prevented.
