Description

[0001] This application has an international filing date of December 30, 2004 and application number PCT / KR2004 / 003515, entitled "Recording medium having physical access control (PAC) information thereon, and methods for forming, recording and reproducing the record Apparatus and method for medium" is a divisional application of the application. technical field

[0002] The present invention relates to PAC (Physical Access Control), PAC areas, PAC clusters, media (for example, high density optical discs such as Blu-ray Discs) containing PAC areas and / or clusters, and methods for recording to and / or from such media Apparatus and method for reproducing data. Background technique

[0003] Media such as optical discs may be used to record large amounts of data. Among various available optical discs, high-density optical media (HD-DVD) which allow recording and / or storage of more high-density video and / or audio data, such as Blu-ray discs (hereinafter referred to as "BD"), are u...

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...
