A recording device according to the present invention has a function (202, 206, 207) of dividing precoded record data into data blocks of a prescribed length to adjust to a magneto-optical disk (3) and adding an intrinsic pattern before and after the data blocks. As the intrinsic pattern, a pattern which reduces a decoding error of maximum likelihood decoding at an end of each data block is used. Therefore, even when data is inserted after precoding, code correlation of a precoded signal can be maintained at a location where division is performed. <IMAGE> |
