Paper Abstract

In the shot noise limited case C/N-ratios of more than 60 dB should be achievable with MO-layers available today. Light ellipticity due to substrate birefringence and phase retardation in the optics reduces the C/N-ratio in practice drastically. With optimized optical set-ups C/N-ratios of 50-54 dB were realized with PC-disks. Local variations of substrate birefringence causes also specific hard errors characterized by peak error amplitudes much higher than the MO-signal. Such errors affect the design of the electronics of the read channel which is demonstrated by a Byte error analysis.
