Abstract

A ray-tracing technique employing Jones matrices was used to model the polarization state of the reflected wavefront as a function of numerical aperture for the various types of magnetooptic media. The average reflectance and MO signal for differential readout were calculated for different numerical apertures by integrating over the wavefront. Quadrilayer structures which are designed to maximize the readout SNR are most affected by incident angle effects.
