Abstract

This paper presents an analytical investigation of the interaction of servo signals (for focusing and tracking) and the substrate birefringence for magneto-optical disk storage systems. Results of the computer simulation using the program DIFFRACT show that spherical aberrations and astigmatism of the beam, and enhancements due to the substrate birefringence have various effects on the feedthrough signal. While some combinations have only minimal effects on track crossing, others could force the disk out of focus before they are nulled out.
