Paper Abstract

High-bit-density optical data storage disks based on reversible crystalline-to-amorphous phase transitions are discussed. Some of the factors controlling the performance of such disks are the signal-to-noise ratio, error rate, and stability, each of which imposes stringent requirements on the active material, geometry, and write/erase/read mechanisms. We have developed a reversible optical data storage disk based on materials in which tellurium or other chalcogens play an important role. Such alloys are called chalcogenide materials, and are highly flexible and capable of independent optimization of the relevant materials parameters. In particular, composition, preparation techniques, chemical modification procedures, and coating methods can be tailored to achieve system optimization. Furthermore, disk geometry, fabrication, and crystallization and vitrification processes can be designed to improve the overall system performance
