Method and apparatus for recording information onto optical disk

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.

Description

technical field [0001] The present invention relates to a method and apparatus for recording information on an optical disc. In particular, it relates to a method of recording different disc information on each optical disc. Background technique [0002] Read-only optical discs such as DVD (Digital Video Disc) have a synthetic resin substrate with a pattern of depressions and protrusions, or so-called depression patterns corresponding to recorded information, and a cover depression pattern. The recording layer is formed of a thin layer of gold, aluminum or similar metal. The pattern of depressions and protrusions of the recording layer is read out by a laser beam, thereby obtaining information such as image, sound, and character data. [0003] As for the formation of the concave pattern on the synthetic resin substrate, the concave pattern previously formed thereon is transferred and formed on the resin substrate by a metal master or the like. Therefore, an optical disc o...

Problems solved by technology

Without continuous management of information on dead numbers, it will be difficult to tell whether later occurrences of dead numbers in serial numbers are attributable to marketing and distribution or to the manufacturing process

In addition, when a disc with a specific identification code is required, the purpose cannot be achieved if the specific identification code does not appear
