DVD that can Store upto 1TB Data?

Even as the world is hard put to decide whether it's HD-DVD or Blu-ray coming next, a Jerusalem-based company called Mempile has reportedly introduced an optical disc about as thick as a standard DVD or slightly thicker, which it claims can store up to 1TB or 1,000GB of data.

What's more, the company claims that once the transition to blue lasers is done, the optical disc will be able to store up to 5TB of data.
Mempile's 1TB DVD sports 200 distinct layers, each offering 5GB of storage space. Unlike in regular DVDs, the layers in this DVD are not stuck together or stacked physically. Mempile claims the discs are made from a polymer variant called polymethyl methacrylate (PMMA), which is a mixture of Perspex, Lucite, and Plexiglass. Incidentally, the discs derive their Yellow color from this compound.

Also unlike typical DVDs wherein 2 dimensions are used to store data, Mempile claims it's DVDs use 3 dimensions in the polymer to store data. Mempile's new technology is currently restricted to WORM or write once, read many. However, the company intends to make read/write drives available in future.

While Mempile's concept is not entirely new, the company claims it's prototypes are already reaching 600GB to 800GB of storage, with 1TB storage expected soon.

However, from an industry perspective, Mempile needs to get it's discs/drives to market soon enough for these not to be overtaken by heavyweight rivals -- HD DVD and Blu-ray...
