Abstract

A mathematical framework is derived for transfer-function analysis of magneto-optic data storage devices. The characteristics of the magneto-optic medium define what portions of the optical system transfer function are important. Several ways to improve the transfer function are analyzed, and several optical systems are compared in respect to relative contrast level versus frequency. Estimates of edge responses and two-point resolution are compared. The system that exhibits the best edge and two-point resolution is a self-masking medium. However, shading bands in the collection optics show excellent response.
