The Brits And Storage
The Brits have succeeded in squeezing a terabyte onto a DVD disk, 10 times what the BluRay disks can currently hold and 50 times the capacity of a double-sided, double-layed DVD.
Nature reports that the disk is called MODS, for Multiplexed Optical Data Storage, and could potentially contain 472 hours of video footage – equivalent to a terabyte, or 1,000 gigabytes, of data. It’s been developed by a team led by Peter Török of Imperial College London.
But there’s a problem: So far the researchers can’t retrieve information from their disk fast enough for video footage. It also won’t be around any time soon: Török believes that MODS disks could hit the shops between 2010 and 2015. And it will be too expensive for the layman, so MODS is more likely to be used by libraries or software companies looking for ways to marshal their huge amounts of data. “The British Library could put all their microfiches onto disks,” Török is quoted as saying. “It will be very good for archiving.”
Mind you, people said that about storage before. By then I’m guessing a terabyte on a DVD is not going to seem all that surprising, or all that expensive.
