A method of making an information recording medium of the invention is that first a scenario template is generated based on an input scenario information and assignments of titles, chapters, programs, and cells are determined. Based on this assignments, a disk information file and video file management information are generated on a hard disk and a recording area of a video file data is allocated. At this time, in the disk information file and the video file management information, management information as to menu information corresponding to the scenario template and recording area of cells to be recorded in the video file data. Therefore, the efficiency of making a multimedia optical disc, such as a DVD, which records still picture data, moving picture data, or audio data such as voice, as a content, can be increased.
