摘要：In a disc drive device () described as a specific embodiment of the presentinvention, ACto ACof ADIP cluster address are associated with AUto AUof an address unit.A high-order digit of a sector address that has a value of 0 in the case of a former-half

cluster (sectors FC to D) and 1 in the case of a latter-half cluster (sectors E to F) isassociated with AUAn address bit ABLG for identifying recording areas of a disc havingplural recording areas for land/groove recording or the like is set at 0. These bits of Auto AUand ABLG are associated with 15 bits sto sfrom the lower side of a 16-bit shiftregister for generating a pseudo-random number. Moreover, 1 is associated with themost significant bit sThus, the error correction capability for high-density recording datacan be improved.
