An ECC block is constituted by RS(248,216,33). Of a data length of 216 bytes (symbols), only 16 bytes are allocated to BCA data and the remaining 200 bytes are used for fixed data having a predetermined value. Using the fixed data of 200 bytes and the BCA data of 16 bytes, parities of 32 bytes (symbols) are caculated. Only the BCA data of 16 bytes and the parities of the former 16 bytes of the 32-byte parities, that is, a total of 32 bytes only, are recorded in a burst cutting area of an optical disc. In decoding, error correction processing is carried out by using the fixed data of 200 bytes. The unrecorded parities of 16 bytes are processed as having been erased. Thus the error correction capability in a burst cutting area of an optical disc can be improved.
An information recording device for recording auxiliary information onto a disc recording medium having a data area for recording main data and a burst cutting area for recording the auxiliary information, the device comprising:
An information recording method for an information recording device which records auxiliary information onto a disc recording medium having a data area for recording main data and a burst cutting area for recording the auxiliary information, the method comprising:
A recording medium having a computer-readable program recorded thereon, which when executed by an information recording device, causes the information recording device to perform a method of recording auxiliary data onto a disc recording medium having data area for recording main data and a burst cutting area for recording the auxiliary information, the method comprising:
