Abstract
An optical disc has a plurality of sectors, where each of the plurality of sectors includes a plurality of frames. A sub information bit value of “0” or “1” is assigned to the plurality of frames constituting a sector, excluding the first and last frames. Edge positions are displaced so that leading/lagging errors appear in accordance with a certain rule when data fields of the frames to which the sub information bit value “1” is assigned are read. Edge positions are displaced so that leading/lagging errors appear in accordance with a reversal of the certain rule when data fields of the frames to which the sub information bit value “0” is assigned are read.
