Soon you could be able to store more mp3s and podcasts in your pocket than you’ll ever have time to listen to. Fujifilm is working on a terabyte (1000 gigabyte) holographic memory, which it expects to launch in 2009. The terabyte holo-memory drive would be no bigger than a sugar cube and could access data much faster than existing memory technologies.
Holographic memory devices store binary bits of data by generating a 3D pattern of light interference inside a crystal or photopolymer, using lasers. Multiple bits can be written and read simultaneously, making the technique potentially very speedy.
