3-D Holographic Rom.
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 Kbits/sec (a recording rate of 180 Mbits/sec was demonstrated using a more advanced setup.) The readout rate is 5.1 Mbits/sec using a single tap, large format CCD array. The surface density at any given spot on the disk is 42 bits/micronmeter2.. 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.
