OPTICAL DATA STORAGE MEDIA CONTAINING METAL AND METAL OXIDE DARK LAYER STRUCTURE

摘要

Optical data storage media containing a "dark" layer structure are disclosed. Layered metals and metal oxides provide a dark background that enhances detection of changes in the data layer of the storage media. Combinations such as chromium metal and chromium oxide, and molybdenum metal and molybdenum oxide are offered as examples of suitable materials.
