Scientists in Australia have succeeded in creating the first graphene-based optical disc. Owing to the magical properties of graphene, were not just talking about a Blu-ray or DVD disc that has had its recording layer replaced with graphene, either were talking about holographic storage with absolutely monumental capacity, intrinsically high security, and apparently the ability to recover the data even when the discs are broken.
Without getting into the complexity of how holographic storage works, its enough to say that it allows for incredibly high storage densities. In this case, the Australians say theyve reached a density of around 0.2 terabits per cubic centimeter, or 3.2 terabits per cubic inch.{View Source}
