Abstract
The quality of the beam of a semiconductor laser diode must remain very high throughout the entire optical path. Small amounts of aberration or polarization conversion can destroy the performance of an optical disk drive. Astigmatism of the laser, birefringence of the substrate, tilt of the objective lens (or of the disk), are some of the factors that can seriously degrade the beam quality. In this presentation, some of the theoretical and experimental results that demonstrate the various effects of the optical path on read/write/erase processes of an optical disk data storage system are described.
