摘要： PROBLEM TO BE SOLVED: To provide an optical disk and its driving device capable of surely detecting a connecting point between a land track and a groove track and exactly correcting the tracking offset in an optical disk of a single spiral land/ groove format. SOLUTION: Physical address areas PID1, PID2, PID3, PID4 are recorded four times in a header area, PID1 and PID2 are arranged on the outer peripheral side displaced by a half of a track pitch from the center of a groove track, PID3 and PID4 are arranged on the inner peripheral side displaced by a half of a track pitch from the center of a groove track and they are made detectable by the difference signal in the radial direction. VFO areas at the heads of the respective PIDs are lengthened by PID1 and PID3, the correction of the tracking offset by means of a sum signal is enabled and the detection of the connection point between the land and the groove by means of the difference signal is enabled from the displacement of PID.

摘要： PROBLEM TO BE SOLVED: To provide a new optical disk that does not cause a decrease in the utilization efficiency of an optical disk by defining an arrangement condition of a boundary between a rewritable area and a dedicated reproduction area to prevent data in the both areas from being mixed and arranging the both areas substantially adjacently or through a land having a fixed width. SOLUTION: This optical disk has both the rewritable area and the dedicated reproduction area. In the rewritable area, lands and grooves are alternately connected on a changing line assumed on a prescribed radius, and the rewritable area is formed by a recording track having one recording track with a pitch Pa formed in a spiral shape. In the dedicated reproduction area, information is prerecorded with continuous mark strings in one recording track with a pitch Pb formed in a spiral shape. The rewritable area and the dedicated reproduction area are changed along the changing line assumed roughly on the radius. COPYRIGHT: (C)2004,JPO
