Abstract
When audio dubbing is implemented, error correction is performed for each ECC block. Therefore, even when one byte of data in an ECC block is rewritten, the whole ECC block to which the byte belongs needs to be read and rewritten. When audio dubbing data is scattered in ECC blocks, almost all ECC blocks, or all the data needs be rewritten in order to record audio dubbing data. By constructing ECC blocks including audio dubbing data so as not to contain original data, it is no longer necessary to read and rewrite unnecessary original data when audio dubbing data is overwritten.
