Abstract
An apparatus for measuring the reflectivity of magnetooptic materials where the complex reflection coefficients of absorbing anisotropic media are determined. Amorphous rare-earth transition metal alloys exhibiting polar Kerr effect are analyzed for use as storage media in erasable optical storage systems.
