Abstract:
In a disc drive device (10) described as a specific embodiment of the present invention, AC0 to AC12 of ADIP cluster address are associated with AU6 to AU18 of 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 0D) and 1 in the case of a latter-half cluster (sectors 0E to 1F) is associated with AU5. An address bit ABLG for identifying recording areas of a disc having plural recording areas for land/groove recording or the like is set at 0. These bits of Au to AU18 and ABLG are associated with 15 bits s0 to s14 from the lower side of a 16-bit shift register for generating a pseudo-random number. Moreover, 1 is associated with the most significant bit s15. Thus, the error correction capability for high-density recording data can be improved.
