Abstract

A research project has been performed, in which a mathematical model for a reversible tri -layer optical memory disk was generated. The disk's reversiblity properties are based on the polycryst aline to amorphous physical phase transition that takes place in the disk's top chalcogenide layer. Given the disk's defining parameters, complex indices of refraction, and layer thicknesses, the model predicts the disks output in terms of a contrast ratio. The output, the contrast ratio, is simply the reflectivity of the chalcogenide in its amorphous state divided by the reflectivity of the chalcogenide material in its polycrystaline state.
