New storage technology can fit 500GB on one disc
Researchers at three European universities—the University of Berlin, the Budapest University of Technology and Economics, and the Universita Politecnicà delle Marche—have developed a new storage technology
that can squeeze 500GB of data onto a single DVD-like disc. As The Register reports, the technology used is called microholographic recording, and it works by etching nano-structures inside the disc itself.
The 500GB disc prototype is made up of 50 storage layers, but there seems to be room for more. According to one of the professors working on the technology, microholographic recording could allow for discs capable of storing 1TB of data. Professor Susanna Orlic claims the technology's goal isn't to store hundreds of movies, though, but "secure long-term storage."
