But for those who desire more space on a highly portable medium, new technology from a company called Mempile in Jerusalem promises to blow these limits away. The company claims that they can store up to 1TB (1,000GB) on an optical disc with the same dimensions—only slightly thicker—than a regular DVD and will be able to store 5TB once the jump to blue lasers is made.
The 1TB disc is divided into 200 different layers, each comprising 5GB of storage space. Unlike standard multilayer DVDs, the layers aren't physically stacked and stuck together. The Mempile discs are solid and use a specially developed variant of the polymer polymethyl methacrylate (PMMA)—a mixture of Perspex, Lucite, and Plexiglass—known as ePMMA. It's this polymer that gives the discs a distinctive yellow color.
The idea itself is not new: other firms have been claiming to be developing this sort of technology for a few years now, but Mempile says that its prototypes are reaching 600-800GB now with 1TB coming soon, and it plans to follow the product up with a blue-laser version that could store up to 5TB
