Design of the optimum optical multilayer coupling of phase-change optical disk

This thesis proposes a detailed design of the optimum optical multilayer coupling of phase-change optical disk. The reflectivity of the multilayer is calculated in accordance with the admittance matrix of optical films, and the computing program is made using a optimization process. The authors advance for the first time a new design in which the second maximum value rather than the first one, serves as a base for the practical multilayer of phase-change optical disk in technology. The number of cycles of erasing and writing of experimental samples based on this design can be more than one million.
