Abstract
In one embodiment, the method includes reading control information including version information from a specific area of the recording medium. The version information includes a first version information and a second version information. At least one of the first version information and the second version information is used to determine a backward compatibility with respect to reading or writing of the recording medium. A recording/reproducing of data on/from the recording medium is controlled based on the version information.
Claims22
A method of recording/reproducing data on/from all optical recording medium, method comprising
- identifying version information, the version information indicating a version of the optical recording medium version information including first version information and second version information, the first version information being represented by “X1.YI” and the second version information being represented by “X2.Y2”, the second version information for indicating a higher version, which is not indicated by the first version information, “X2” of the second version information being equal to or higher than “XI” of the first version information, and “X2.Y2” of the second version information being higher than “X1.YI” of the first version;
- and
- determining a compatibility between the optical recording medium and a drive for recording/reproducing the data, based on the first version information and recording/reproducing the data on/from the optical recording medium,
- wherein the first version information represents a compatible version of the optical recording medium, and the second version information represents an actual version of the optical recording medium;
- and
- recording, by a recording/reproducing apparatus, the version information on a specific area of the optical recording medium.
3 more elements
An apparatus for recording/reproducing data on/from an optical recording medium, the apparatus comprising:
- a pickup unit configured to record version information on a specific area of the optical recording medium, the version information indicating a version of the optical recording medium, the version information including a-first version information and a-second version information, the first version information being represented by “X1.YI” and the second version information being represented by “X2.Y2”, wherein “X2” of the second version information is equal to or higher than “XI” of the first version information, and “X2.Y2” of the second version information is higher than “X1.YI” of the first version information;
- and
- a controller configured to control the pickup unit to record the version information on the optical recording medium, wherein the controller is configure to determine a compatibility between the optical recording medium and the recording/reproducing apparatus based on the version information to record/reproduce the data on/from the optical recording medium according to the determined compatibility,
- wherein the first version information represents a compatible version of the optical recording medium, and the second version information represents an actual version of the optical recording medium.
1 more element

- a specific area storing version information, the version information indicating a version of the optical recording medium, the version information including first version information and second version information, the first version information being represented by “X1.YI” and the second version information being represented by “X2.Y2”, the second version information for indicating a higher version, which is not indicated by the first version information,
- wherein “X2” of the second version information is equal to or higher than “XI” of the first version information, and “X2.Y2” of the second version information is higher than “X1.YI” of the first version information;
- determining a compatibility between the optical recording medium and the apparatus based on the first version information;
- and recording/reproducing the data on/from the optical recording medium according to the determined compatibility,
- wherein the first version information represents a compatible version of the optical recording medium, and the second version information represents an actual version of the optical recording medium;
- and
- recording, by a recording/reproducing apparatus, the version information on a specific area of the optical recording medium.
4 more elements
