Abstract
A once-recordable optical disk has a data recorded area in which application software for creating an information group and a first file system are prerecorded. The application software is readable with the first file system and is used to select desired ones from among information pieces stored in a personal computer and form the information group. According to instructions from the application software, a second file system and the information group readable with the second file system are written in a blank area of the optical disk. After the creation of the information group, the application software and first file system in the optical disk are disabled so that they are unreadable with the second file system.
