摘要：
An optical disc includes tracking polarity information. The optical disc includes a clamping area, a lead-in area, a data area, and a burst cutting area (BCA). The BCA is present between the clamping area and the lead-in area and in which information regarding the optical disc is recorded, and the information is read before performing tracking in the data area. Accordingly, it is possible to obtain the tracking polarity information and/or reflectivity information without trial and error and directly record or reproduce user data in a data area of the optical disc.
