Abstract:

Holoplex has designed and constructed a 3-D holographic WORM disk system capable of stand-alone operation or used to produce master disks for mass-produced holographic ROM HROM systems. The storage capacity of die current system Is 0.33 Tbits per 12 cm diameter disk. The recording rate is 240 Kbitssec a recording rate of 180 Mbitssec was demonstrated using a more advanced setup. The readout rate is 5.1 Mbitssec using a single tap, large format CCD array. The surface density at any given spot on the disk is 42 bitsmicronmeter2.. This is achieved by multiplexing 84 holograms per location using a combination of peristrophic and angle multiplexing techniques. The entire setup was construed from readily available off-the-shelf components and a pair of custom designed imaging lenses.
