Fujifilm Will Manufacture 1TB Optical Discs
FujiFilm is now working on increasing the capacity of optical discs up to 1TB to put them on the market by 2015 (at present the largest ones are 50Gb). The company has lately developed a new recording method for optical discs by using two-photon absorption technique to produce heat: the two-photon absorption can be limited to the small area of the focal point of a laser light. This innovative method would allow them to expand the recording layers up to 20 on each side of a disc. FujiFilm claims there’s good reason to think to make a double-sided optical disc with a 1TB storage capacity. It takes 147 seconds to form a four-layer Blu-ray Disc; it takes only 58 seconds to form eight layers using their method. In the future it will be possible to make a 15-TB optical disc (25 Gbytes/layer x 3 (eight values) x 100 layers x 2 (two sides). Interesting is, that according to FujiFilm the cost of manufacturing of this new disc will be cheaper than blu-ray discs.
