Abstract

A recording medium and an apparatus for recording / reproducing data on the recording medium, which are capable of controlling access to the recording medium by recording control information for controlling access for reading the data, are disclosed. When a function included in the recording medium cannot be performed, Unknown Rules are applied, and, when the function included in the recording medium can be performed, Known Rules are applied. Even in the Known Rules, a password may be used such that data reading is controlled. Accordingly, it is possible to compatibly reproduce the data from different versions of recording media. It is difficult for a user to access to the recording medium such that content protection can be improved.

Description

technical field

[0001] The present invention relates to a recording medium and an apparatus and method for recording / reproducing data on / from the recording medium, and more particularly, relates to a method for recording / reproducing data on / from the recording medium while controlling access to the recording medium. An apparatus and method for recording / reproducing data on a medium. Background technique

[0002] In general, an optical recording / reproducing apparatus records / reproduces data on / from a magnetic disc such as a compact disc (CD), digital versatile disc (DVD), or blu-ray disc (BD). As consumer preferences have changed, there is a need for a technique for processing high-definition moving images. In addition, since moving image compression techniques have been developed, high-density recording media are required. Recently, new high-density recording media are being developed that enable long-term recording and storage of high-definition video and audio data. [0...
