    摘要： An optical disc using a single-spiral land and groove track format enabling accurate tracking offset correction and reliable detection of the transition point between a land track and a groove track, and a driving apparatus therefor, are disclosed. Four physical address areas PID1, PID2, PID3, and PID4 are recorded to a header area such that PID1 and PID2 are offset one-half track pitch toward the outside circumference of the disc from the groove track center, and PID3 and PID4 are offset one-half track pitch toward the inside circumference of the disc from the groove track center, and the physical address areas PID1 - PID4 can be detected by means of a difference signal in the radial direction. The single frequency pattern area VFO at the beginning of each PID is lengthened by PID1 and PID3, thereby enabling tracking offset correction using a sum signal, and detection of the land-groove transition point using a difference signal obtained from the PID offset. The frequency of the VFO pattern may be set lower than the highest frequency of the channel bit sequences of the modulation method used on the disc. Address marks may employ a channel bit pattern which includes two sequenses which are longer than the longest mark length of the modulation method.
