Embodiment Construction

[0035] Best Mode for Carrying Out the Invention

[0036] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0037] figure 1 A PAC area on a high-density optical disc according to an exemplary embodiment of the present invention is shown.

[0038] see figure 1 , the high-density optical disc can be partitioned from the inner circle to the outer circle into a lead-in area, a data area and a lead-out area. The lead-in area can be further partitioned into an INFO2 area and an INFO1 area above for recording various information. The INFO2 area and / or the INFO1 area may include a PAC (Physical Access Control) area.

[0039] For convenience, the PAC area allocated to the INFO2 area is marked as the PACII area, and the PAC area allocated to the INFO1 area is marked as the PACI are...
