Abstract
A recording medium, such as a high-density and/or read-only recording medium, such as BD-ROM, which includes copy protection indicating information, which can identify whether copy protection information is needed or not for the playback of contents stored on the recording medium, and to methods and apparatuses for forming, recording, and reproducing data on the recording medium.
Claims40
A recording medium including recorded data, comprising:
- copy protection indicating information indicating whether or not the recording medium contains copy protection information for use in decrypting the recorded data, wherein the copy protection indicating information and/or the copy protection information are recorded in wobbled pre-pit pattern on an area of the recording medium.
A method of forming a recording medium, comprising:
- forming a recordable area for storing recorded data;
- forming an area on the recording medium for storing copy protection indicating information indicating whether or not the recording medium contains copy protection information for use in decrypting the recorded data, wherein the copy protection indicating information and/or the copy protection information are formed as wobbled pre-pit pattern on an area of the recording medium.
A method of reproducing data from a recording medium, comprising:
- utilizing copy protection indicating information to indicate whether or not the recording medium contains copy protection information for use in decrypting the data, to reproduce the data, wherein the copy protection indicating information and/or the copy protection information are recorded in wobbled pre-pit pattern on an area of the recording medium.
A method for playing data of a recording medium, comprising:
- detecting copy protection indicating information indicating whether or not the recording medium contains copy protection information for use in decrypting the data, wherein the copy protection indicating information and/or the copy protection information are recorded in wobbled pre-pit pattern on an area of the recording medium;
- and
- playing the data utilizing the copy protection information if the recording medium contains copy protection information for use in decrypting the data, or playing the data directly without utilizing the copy protection information, if the recording medium does not contain copy protection information for use in decrypting the data, based on the detected copy protection indicating information.
A method of recording data on a recording medium, comprising:
- utilizing copy protection indicating information to indicate whether or not the recording medium contains copy protection information for use in decrypting the data wherein the copy protection indicating information and/or the copy protection information are recorded in wobbled pre-pit pattern on an area of the recording medium.
An apparatus for reproducing data from a recording medium, said apparatus utilizing copy protection indicating information to determine whether or not the recording medium contains copy protection information for use in decrypting the data, to reproduce the data based on the copy protection indicating information and the copy protection information, wherein the copy protection indicating information and/or the copy protection information are recorded in wobbled pre-pit pattern on an area of the recording medium.
An apparatus for reproducing data from a recording medium, comprising:
- a detector detecting signals recorded on the recording medium, the signal including copy protection indicating information to determine whether or not the recording medium contains copy protection information for use in decrypting the data, wherein the copy protection indicating information and/or the copy protection information are recorded in wobbled pre-pit pattern on an area of the recording medium;
- and
- a signal processor for playing the data utilizing the copy protection information if the recording medium contains copy protection information for use in decrypting the data, or playing the data directly without utilizing the copy protection information, if the recording medium does not contain copy protection information for use in decrypting the data based on the copy protection indicating information.
