This invention discloses a protective disc and structure to hold an optical data disc to the protective disc so that if the during use the combination of the data disc and protective disc are mishandled the protective disc does not permit the data to become scratched. Instead the protective disc might become scratched. The data disc is held to the protective disc in a releasable fashion so that it can be removed from the protective disc and attached to another if the first protective disc becomes scratched. The data disc can be held to the protective disc by a band which extends entirely around the circumference of a data disc. The band can be comprised of two semicircular rings which are held together by hinges and/or by clasps so that as the semicircular rings are brought together they surround the edges of the protective disc and the data disc and hold the discs together. Alternatively, the band can be made of a continuous ring of heat shrink material. In this instance the band is applied around both the protective disc and the data disc, and then heat is supplied so as to shrink the band around the discs and hold them together.
