3D Atomic Holographic Storage
Colossal Storage Corporation has dominant patents the first patents issued in any field that details a totally new concept for a Ultra-Violet/Deep Blue Laser integrated semiconductor R/W Head used for non-contact rewritable data to a ferroelectric optical holographic removable storage product.
Colossal Storage wants its Rewritable 3D Volume Atomic Holographic Removable Optical Storage NanoTechnology to be an " ALL IN ONE " Storage Solution replacing Ram, Rom, DRAM, FRAM, MRAM, Ovonic, Flash, 2D Optical Drives(phase change/MO DVD), Tape Drives, AFM/ATF and Hard Drives for " ALL IN ONE " complete system hardware storage requirements.
All holographic storage technology except Colossal Storage Corp. use a spatial light modulator (SLM) made from ferroelectric lithium niobate which writes one complete page of data at a time.
When you need to change ONE BIT USING SLM it is necessary to almost rewrite the ENTIRE DISK !
