Compared to a C-ROM's meager 700 MB storage space, and a DVD's 5-ish GB, a Blu-Ray's 25 GB is pretty impressive. All of those are nothing compaired to a whole Terabyte though, and that's what FujiFilm is planning to pack on an optical disc arriving in 2015.
This isn't the first time we've heard about the fabled 1 TB optical disk. TDK was talking about one back in 2010, but it still hasn't come to market almost three years later. FujiFim, on the other hand, predicts they'll be able to get theirs on shelves in two years, with the possibility of 15 TB discs not that much further behind.
These mammoth discs rely on a special two-photon absorption technology as well as other manufacturing advancements can allow for the production of discs with 25 GB layers, and up to 20 of those on each side. As if that wasn't enough, FujiFilm predcts these new discs will actually be cheaper to make than Blu-Rays. Obviously this is still in the works, and we're still waiting on those 1 TB discs we heard about three years ago, so no one will blame you for being a little skeptical. Still, a 1 TB disc sounds great even two years down the line, so long as flash memory hasn't completely out-paced it by then. [PhysOrg]
