Abstract

Calculations of the reflectance, transmittance, Kerr magneto-optical polarization rotation, and related constants are important in the design of multilayer thin-film media for magneto-optical disks for data storage. Different computation methods have been suggested in the literature for specific structures.1-3 We have established a powerful technique based on matrix methods and have written a program to calculate all the optical responses of multilayer structures. Calculations for a few specific models have been made, and these predict Kerr rotation angles > 2° for normal incidence. These calculations can be readily extended to different media structures. Oblique incidence calculations are also being incorporated. We feel that disk media designs can be analyzed very effectively with this technique.
