Patent ID: 7613986

Claim:
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 input terminal configured to acquire the auxiliary information, wherein said auxiliary information consists of 16 bytes; an error correcting code circuit configured to generate error correction blocks corresponding to the auxiliary information using a Reed-Solomon error correcting code that has a same code length of 248 bytes, data length of 216 bytes and distance of 33 bytes as an error correcting code of the main data recorded in the data area, the auxiliary information having the length of 16 bytes which is smaller than the data length of 216 bytes of the Reed-Solomon error correcting code and fixed data filling the remaining length of 200 bytes of an error correction block; the error correcting code circuit configured to calculate parities of 32 bytes using the fixed data having the length of 200 bytes and the auxiliary information having the length of 16 bytes; a modulator configured to modulate the auxiliary information having the length of 16 bytes and 16 bytes of the 32 bytes of calculated parities; and a laser configured to record the auxiliary information having the length of 16 bytes and the 16 bytes of the 32 bytes of calculated parities modulated by the modulator, into the burst cutting area on the disc recording medium.
