Abstract

The effects of incident angle on the readout SNR of a magnetooptic storage system employing the differential detection system were theoretically investigated. The most important parameters which depend on incident angle were found to be the Kerr reflectance and the phase difference between the two components of the reflected wave. In particular, the phase difference was found to depend strongly on incident angle for structures which are strongly antireflective.
