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.
