Information recording medium, information recording device and method, information recording control program, and recording medium containing the information recording control program

Abstract

On a recording medium, the version information indicating a version of the recording standard to which the information recording medium is adapted is recorded. Moreover, the normal recording condition information for recording information at a normal recording speed and the high speed recording condition information for recording the information at a higher recording speed than the normal recording speed are recorded. The recording condition information includes, for example, information about a write strategy for driving a laser light source. At the time of recording, the information recording device compares the version information on the information recording medium with the version information of the information recording device so as to judge whether or not the information can be recorded. When the judgment is made that the information cannot be recorded based on the version information, further the compatibility version information is compared with the version information of the information recording device so that a judgment is made as to whether or not the information can be recorded. In such a manner, the judgment can be properly made as to whether or not the recording can be executed on the information recording medium.An information recording medium contains version information indicating to which version of the recording specification the information recording medium corresponds. Moreover, the medium contains standard recording condition information for recording information at a standard speed and high-speed recording condition information for recording information at a higher speed. An information recording device compares the version information on the information recording medium to the version information of the information recording device side to judge whether information recording is enabled. When it is judged that information recording is disabled according to the version information .

Description

technical field [0001] The present invention relates to an additionally writable or rewritable recording medium such as DVD-R (DVD Recordable) and DVD-RW (DVD Rewritable) and methods for recording information in the recording medium An information recording device and an information recording method. Background technique [0002] DVD-R and DVD-RW are well known as information recording media on which information can be written or rewritten multiple times. On such an information recording medium, information related to the recording speed and recording conditions applicable to the information recording medium is recorded. Specifically, part version information for defining a recording standard suitable for a disc recording method is recorded in the control data area of ​​the DVD-R or DVD-RW lead-in area. The component version information indicates the version of the DVD recording standard adopted by the disc. [0003] Meanwhile, a drive device (information recording device...
