Abstract
A writing unit divides a sync byte into two sync bytes of a first sync byte and a second sync byte and also divides write data into two data of first data and second data and writes them. When a first sync byte pattern is detected, a reading unit demodulates the subsequent first data, second data, and an error detection correction code. When the first sync byte pattern SB1 is not detected but a second sync byte pattern SB2 is detected, the subsequent second data and error detection correction code are demodulated and the first data is reconstructed by the error detection correction code.
