Depending on the location of the scratch and the type of digital information contained, it may not be possible to use a scratched optical disc because it may cause equipment that uses digital information on the optical disc to malfunction. Without a duplicated optical disc, the recorded digital information itself could be lost, causing serious damage. In addition, even if there is a duplicated optical disk, an optical disk containing the same content of digital information is purchased repeatedly, which is economically and materially wasteful.

In addition, when the protective film surface 5 is scratched 4, the protective film 3 is peeled off, and another intact protective film is adhered, so that the protective film surface 5 of the optical disc 1 is smooth without any damage. It is possible to restore the condition.

的な無駄も無くなった。According to the optical disk of the present invention, it is possible to prevent the surface of the optical disk from being damaged and to replace the protective film with another intact protective film even if the surface of the protective film is damaged. As a result, the digital information recorded on the optical disk can be completely read by removing the scratches, so that the digital information recorded on the optical disk will not be lost, and the digital information of the same content will not be lost. The economical and material waste of repeatedly purchasing recorded optical disks has been eliminated.
