Embodiment Construction

[0028] Best Mode for Carrying Out the Invention

[0029] Reference will now be made in detail to the exemplary embodiments of the present invention which are illustrated in the accompanying drawings. Wherever possible, the same numbers will be used throughout the drawings to identify the same or like parts.

[0030] FIG. 1 illustrates a PAC area on a high-density optical disc according to an exemplary embodiment of the present invention.

[0031] Referring to FIG. 1 , a 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, on which various types of information are recorded. The INFO2 area and the INFO1 area may include a PAC (Physical Access Control) area.

[0032] For convenience, the PAC area allocated to the INFO2 area is marked as the PAC2 area, and the PAC area allocated to the INFO1 area is marked as t...

Abstract

A recording medium, such as a high-density and / or optical recording medium, including segment information recorded thereon, and an apparatus and method for recording to or reproducing from the recording medium, for enhanced data protection, data management and / or reproduction compatibility.

Description

[0001] The application date is "March 3, 2005", the application number is "200580008681.5", and the title is "Recording medium with segment information thereon, and apparatus and method for forming, recording and reproducing the recording medium" divisional application. technical field [0002] The present invention relates to managing physical access control (PAC) and recorded data, media containing PAC and recorded data (e.g., high-density optical discs such as Blu-ray discs), and methods for recording data to and / or reproducing data from the media Apparatus and methods. Background technique [0003] Media such as optical discs may be used to record large amounts of data. Among the available optical discs, new high-density optical media (HD-DVD) such as Blu-ray Disc (hereinafter referred to as "BD") are being developed, which allow recording and / or storage of more high-definition video and / or or audio data. [0004] BD also includes Blu-ray Disc Rewritable (BD-RE), Blu-...
