PURPOSE:To make operation of an operator simple by displaying information that correlates the body of an information storing medium and a cassette in a display section provided in the cassette and storing it in an information storing layer of the body of the information storing medium. CONSTITUTION:To manufacture an information storing medium, an optical disk 13 is inserted into a disk cartridge 12 manufactured separately and a bar code 15 that indicates information of manufacture corresponding to the inserted optical disk 13 is stuck on the side of the cartridge 12. Manufacture's serial number and date of manufacture of the optical disk 13 are read optically from the bar code 15, and read data are stored optically in the information storing layer of the disk 13. Thereby, troubles such as key inputting the number and data of manufacture etc. can be reduced, and accordingly, storing process can be simplified, and efficiency of operation of an operator can be heightened. Further, a computer that generates stored data corresponding to the number and date of manufacture by key inputting becomes unnecessary, and whole manufacturing unit can be made small. |
