Abstract
A figure of merit is derived for the magneto-optical media used in erasable optical data storage. It is shown that the ratio of the useful signal generated by the polar Kerr effect to the incident laser power is always below the figure of merit, but the figure can be approached if the magneto-optic medium is embedded in a proper multilayer structure.Keywords
