摘要： In optical disk having a track formed of groove tracks and land tracks connected every revolution to form a single spiral, each revolution-of the tracks is divided into sectors, each having identification signal region at the head of the sector, and the identification signal regions in tracks adjacent to each other are aligned in the radial direction. Prepits are formed in the identification signal region, on an extension of a boundary between groove and land tracks adjacent to each other. The prepits have a width substantially equal to the width of the grooves. The identification signal including address information of the sector. The polarity of tracking error signal is detected at the identification signal region of the recording sector, and whether the recording sector is in a groove track or land track is determined based on the polarity of tracking error signal. The identification signal may include information concerning the timing for switching tracking polarity in accordance with whether groove or land sector is being scanned.

摘要： In an optical disk having information recording tracks of lands and grooves, the grooves are wobbled in a radial direction of the disk so as to represent rotation information and sector management information, at least one pair of a wobbling part and an unwobbling part arranged one after another are provided every revolution, such that the wobbling parts in the grooves next to each other do not overlap in the radial direction of the disk. Since the wobble parts in the grooves next to each other do not overlap in the radial direction, the wobble data can be obtained regardless of whether a beam spot is tracing a land track or a groove track, and even in a data part of each sector.

摘要： The invention provides an optical disk medium having a recording spiral formed by connecting groove tracks and land tracks alternately, and permitting detection of a connecting point between a groove track and a land track reliably is provided, and a method of tracking the optical disk medium and an optical disk drive apparatus for driving the optical disk medium. One part of an identification signal area is shifted by a predetermined distance in one radial direction from the center of a groove, while another part of the identification signal area is shifted by the same distance in the opposite radial direction from the center of the groove. A land/groove polarity of a sector is determined by the polarity of a tracking error signal and the order of the polarities during reproduction of an identification signal.
