Optical channel modeling for InSb-based super-resolution disc storage

A complete optical channel model of a super-resolution optical disc system is developed that includes not only the optical pick-up but also the super-resolution disc, using InSb for the mask layer. This is a candidate technology for a next generation of optical discs after the Blu-ray Disc. Model parameters have been derived to match former static experiments. The model is extended to a moving disc. The impulse response of the optical channel is determined from the model and compared with real disc readout data. The model provides a link from physics to electronic signals and allows performance analysis of a mask layer material in question already before optical drive development.
