Abstract
A writing unit writes a first sync byte pattern SB1 to the head of data and writes a second sync byte pattern SB2 to the end of the data (DATA+ECC). When the first sync byte pattern SB1 is not detected, the data is stored into a memory, and after that, a reading unit reads out the second sync byte pattern SB2 in the memory. When the second sync byte pattern SB2 is detected, the reading unit reads out the data of a predetermined length DL in which a position that is preceding to the detecting position by only a predetermined data length (DL) is set to the head position from the memory and demodulates.
