Paper Abstract

Volumetric memories based on the extension of conventional approaches by using the third dimension for multiple layers may offer dramatic increases in storage capacity. For such thick- media multilayer systems, the design of the optical head includes challenges in the control and tolerancing of aberration accumulation throughout the focal depth. In this paper we review the accumulation of these aberrations in high resolution thick disk media, and compare the tradeoffs associated with several aberration compensation techniques. Both analytical and simulation results of aberration accumulation as a function of the system f-number will be presented. Aberration compensation tradeoffs including compensator complexity, cost, compensation range, speed will b detailed. Simulation results of a compensation technique will be presented.
