Abstract
In one embodiment, the method includes generating version information including a first version information and a second version information. At least one of the first version information and the second version information is to determine a backward compatibility with respect to reading or writing of the recording medium. The version information is recorded on a specific area of the recording medium.
Claims21
A method of recording version information of a recording medium, comprising:
- generating version information including first version information and second version information, wherein at least one of the first version information and the second version information is to determine backward compatibility with respect to reading or writing of the recording medium;
- and
- recording the version information on a specific area of the recording medium,
- wherein the first version information represents a compatible version, and the second version information represents an actual version,
- the first version information being represented by “X1.Y1” 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 “X1” of the first version information, and “X2.Y2” of the second version information being higher than “X1.Y1” of the first version information,
- wherein the first version information is included in one information byte, and the second version information is represented by one information byte.
A recording medium including a data structure for version information, the version information including first version information and second version information, at least one of the first and second version information is used to determine a backward compatibility with respect to reading or writing of the recording medium,
- wherein the first version information represents a compatible version, and the second version information represents an actual version,
- the first version information being represented by “X1.Y1” 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 “X1” of the first version information, and “X2.Y2” of the second version information being higher than “X1.Y1” of the first version information,
- wherein the first version information is included in one information byte, and the second version information is represented by one information byte.
An apparatus for recording version information on a recording medium, comprising:
- a controller configured to generate version information including first version information and second version information, at least one of the first version information and the second version information is to determine backward compatibility with respect to reading or writing of the recording medium;
- and
- a recording part configured to record the version information on a specific area of the recording medium,
- wherein the first version information represents a compatible version, and the second version information represents an actual version,
- the first version information being represented by “X1.Y1” 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 “X1” of the first version information, and “X2.Y2” of the second version information being higher than “X1.Y1” of the first version information,
- wherein the first version information is included in one information byte, and the second version information is represented by one information byte.
