Abstract:
According to one embodiment, address information is expanded on a bit map in order to generate original address information which is divided in a direction of the abscissa to form groups. The demodulated values of the original address information are obtained as original intra-group demodulated values. New address information is obtained and an arrangement pattern of bits in the servo area determined based on the new address information on a bit map formed by integrating obtained new address information items of the groups.
