Abstract
A method for recording, onto an optical disk, individual information different from optical disk to optical disk, which includes obtaining individual information to be recorded onto an optical disk, writing a bar code corresponding to the individual information into a recording layer within the optical disk with laser beam, reading the individual information of the bar code written in the write process, and comparing the individual information read in the read process with the individual information to be written, wherein if two articles of individual information are coincident with each other, processing on the optical disk is completed and the information obtaining process and the write, read, and compare processes are iterated on a new optical disk, and if the two articles of individual information are different from each other, the current write, read, and compare process are iterated on a new optical disk.
