Abstract

The contributions to noises in optical disk readout caused by the surface roughness on the disk are calculated using a full vector diffraction theory. The sources of noise are assumed to be small periodic bumps existing on land or groove, as well as periodic jaggedness on the groove walls. Under these conditions, the polarization dependence of noise, the difference of noise when the bumps are on land or groove, and the depolarization noise in magneto-optical readout are calculated.
