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.
Claims12
An information recording method comprising:
- installing application software that is for creating an information group and is readable with a first file system into an information processor from a data recorded area of a once-recordable optical disk where the application software and first file system are prerecorded;
- creating the information group by carrying out predetermined processes with the application software in the information processor;
- and
- according to instructions from the application software, writing a second file system conforming to a predetermined optical-disk-standard format and the created information group readable with the second file system into a blank area of the optical disk and making the application software and first file system in the data recorded area of the optical disk unreadable with the second file system.
An information recording method comprising:
- installing application software that is for creating an information group and is readable with a first file system into an information processor from a data recorded area of a rewritable optical disk where the application software and first file system are prerecorded;
- creating the information group by carrying out predetermined processes with the application software in the information processor;
- and
- according to instructions from the application software, writing a second file system conforming to a predetermined optical-disk-standard format over the data recorded area of the optical disk to thereby partly or entirely delete the first file system and application software in the data recorded area and writing the created information group readable with the second file system in a rewritable area of the optical disk.
An information recording method comprising:
- installing application software that is for creating an information group and is readable with a file system conforming to a predetermined optical-disk-standard format into an information processor from a data recorded area of a rewritable optical disk where the application software and file system are prerecorded;
- creating the information group by carrying out predetermined processes with the application software in the information processor;
- and
- according to instructions from the application software, modifying data in the file system upon the creation of the information group, writing the modified file system over the data recorded area of the optical disk to thereby partly or entirely delete the file system and application software in the data recorded area, and writing the created information group readable with the modified file system in a rewritable area of the optical disk.
An optical disk comprising a once-recordable data recorded area in which application software for creating an information group and a first file system for reading the application software are prerecorded,
- the application software having functions of being read in an information processor with the first file system, carrying out predetermined processes to create the information group, writing a second file system conforming to a predetermined optical-disk-standard format and the created information group readable with the second file system into a blank area of the optical disk, and making the application software and first file system stored in the data recorded area of the optical disk unreadable with the second file system.
An optical disk comprising a rewritable data recorded area in which application software for creating an information group and a first file system for reading the application software are prerecorded,
- the application software having functions of being read in an information processor with the first file system, carrying out predetermined processes to create the information group, writing a second file system conforming to a predetermined optical-disk-standard format over the data recorded area of the optical disk to thereby partly or entirely delete the first file system and application software in the data recorded area, and writing the created information group readable with the second file system in a rewritable area of the optical disk.
An optical disk comprising a rewritable data recorded area in which a file system conforming to a predetermined optical-disk-standard format and application software that is readable with the file system and is used to create an information group are prerecorded,
- the application software having functions of being read in an information processor with the file system, carrying out predetermined processes to create the information group, modifying data in the file system upon the creation of the information group, writing the modified file system over the data recorded area of the optical disk to thereby partly or entirely delete the file system and application software in the data recorded area, and writing the created information group readable with the modified file system in a rewritable area of the optical disk.
