There is a great deal of interest at the present time in materials appropriate for use in optical data storage systems. The bulk of this effort over the last few years has been concentrated on materials that can be thermally ablated using a tightly focused laser beam. To date the majority of this work has dealt with tellurium and tellurium-based alloys because of their unique thermal properties. Other thin film metals and alloys have also been studied, but tellurium-based systems show the most promise to date. More recently organic-based systems, such as neat dyes and dye- or carbon-loaded polymers, have been explored.
