ABSTRACT:
A novel optical media is provided for use in an optical recording and reproducing system. The optical media comprises a tuned multilayer optical structure employing an archival thin film absorber having a relatively high melting point, such as gold, along with an in-contact overcoat. The characteristics of the media are chosen so as to permit use of a specially chosen hole-forming data recording mechanism which permits recording optically detectable data in the media without requiring heating of the absorber material to its bulk melting point, and also without requiring ablation of the absorber material, whereby compatibility with the in-contact overcoat is also achieved.
