Blu-ray and HD DVD have pushed the limits of optical storage further than anyone thought possible. But a new technology has emerged which makes Blu-ray's 50GB capacity look tiny. Mempile in Israel says it's able to fit an incredible 1TB of data onto one "TeraDisc" which is the same size as CDs and DVDs. That's 20 times the capacity of a maxed-out dual-layer Blu-ray disc.
The incredible capacity achieved using this new technology is made possible by employing 200 5GB layers, each one only five microns apart. The discs are completely transparent to the red lasers which are used in the associated recorder. Prototypes have already been made to store up to 800GB of data, and Mempile says it will crack the 1TB barrier before moving on to build 5TB blue laser disks. Dr. Beth Erez, Mempile's Chief Marketing Officer says that the first 1TB disks have a lifespan of 50 years and could be on the shelves in two to three years.
