LENS DESIGN ISSUES IMPACTING PAGE ACCESS TO VOLUME OPTICAL MEDIA

Lens designs are discussed for page access to data stored in volume op tical media. Optimizations of a 4F optical storage system are performe d. These optimized designs are evaluated for degree of parallelism ach ieved, capacity, storage media volume, information storage density, an d overall system volume. We find that the primary effect of aberration s is not to reduce memory capacity but to increase system volume resul ting in lower overall storage density.
