Benefits of technology

[0016] It is therefore an object of the present invention to provide an information recording medium, an information recording apparatus, an information recording method, and a computer program, in which information can be efficiently recorded onto the information recording medium, for example, and which can reduce a recording time. Means for Solving the Subject (Information Recording Medium)
[0068] According to the information recording apparatus of the present invention, it is provided with the pre-recording device, the flag recording device, and the information recording device. According to the information recording method of the present invention, it is provided with the pre-recording process, the flag recording process, and the information recording process. Therefore, it is possible to efficiently record the information onto the information recording medium, and it is also possible to reduce a recording time.

Problems solved by technology

Thus, there is such a technical problem that even if the length of the lead-out area is reduced or the high-speed recording is performed in the lead-out area, it is inevitable that it takes time to perform the recording in the lead-out area.
