OPTICAL DISC HAVING TRACKING POLARITY INFORMATION, AND APPARATUSES AND METHODS FOR RECORDING AND REPRODUCING USER DATA ON THE SAME |
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 are a and in which information regarding the optical disc is recorded, and the information is read before performing tracking in the data area.
