Atomic Holographic Nanotechnology will Set the Pace for the Future

No disk drive product today or tommorrow can equal this performance.

This method of reading / writing offers probably the highest potential of data storage by interference diffraction of light photons from the internal atoms of the molecule.

The signal to noise S/N ratios for ferroelectric storage will be higher and the data bit densities theoretically capable of reaching > 400 Terabits/in2. on a 2D area surface layer as shown by the TDK's CONTACT Recording AFM (atomic force microscope) concept as well as Pioneers , which Colossal feels its use of a fragile R/W probe, slow positioning, low data transfer, contact recording, and 2D Area technology will have reliability issues.

Colossal's 3D Volume Non-Contact patented nanotechnology with > 100 bits versus 1 bit on TDK's Contact AFM ferroelectric film disk will take the densities > 40,000 Terabit/cu.cm. or 40,000,000 Gigabits/cu.cm. per 100 molecule vertical layers with billions of molecule layers being realized and bandwidth > 1000 Terabits/sec.

Colossal Storage will first offer >10 Terabytes and above on a 3.5 in. disk with non destructive read out from the dipole dieletric molecules. By reading the interference patterns (light and dark lines on the photo transistor or diode and comparing the patterns against systems stored hologram patterns extremely fast bandwidths of >1000 gigabits and up can be easily achieved.

Writing to the molecule using UV laser source diode and a data transfer electric field transducer is still non volatile with the addition of the second laser diode as an option for assisted writing power or data manipulation if necessary.

Reading of page stored data allows for reading of 400 molecules (data bits) per 200 nanometer UV photon spot or 50,800,000 bpi and track densities exceeding 25,000,000 tpi.

All holographic storage technology except Colossal Storage Corp. use a spacial light modulator (SLM) made from ferroelectric lithium niobate which writes one complete page of data at a time to the disk.

When you need to change ONE BIT USING SLM it is necessary to almost rewrite the ENTIRE DISK !

Since ALL other holographic storage technology use a spacial/spatial light modulator (SLM) which writes one complete page of data at a time. The data must loaded serially to the SLM and is destructively written so any mistakes on the serial loaded SLM means increased wasted write data time. This method is great for WORM data storage but when BIT FOR BIT Erase / Write / and Read of random data to a disk is needed in real time day to day applications the SLM concept will NOT be able to function.

Colossal Storages method for writing is like having billions of verical spatial light modulated pages in one rewritable ferroelectric track, each track having billions of SLM's. Imagine having billions of SLM on the disk where the data is written / read in bit / byte / word accurately everytime at atomic light speeds.

Colossal Storage has developed many other techniques for recording using ferroelectrics and will publish these techniques in the next few months Abstract of nanoTechnology .
