[QUOTE]Originally posted by Nimrod: [QB] Sorry, the science mag I took the info from seems to be in fault. Here's some newer data, from an article at SysOpt.com "FMD is an acronym which stands for Fluorescent Multilayer Disc. Whereas current DVD reflective technology only writes data to two layers on a CD, FMD technology allows data to be stored in multiple layers on a CD (up to 20 right now, and potentially up to 100 within a few years), while utilizing a red laser which maintains backwards compatibility with current CD, CD-R, and DVD formats. Since each layer of a DVD data density format disc can store 4.7GB of data, 20 layers means approximately 95GB of storage on a single disc, with an access speed of 50-60ms and a data transfer rate of approximately 1 Gigabit per second. Constellation 3D's research has shown that 100 layers are possible, which would allow a single 120mm CD to store 450GB+. If a blue laser was utilized (which has a smaller wavelength than red laser, but is currently expensive to manufacture and too hot for consumer applications), 1 TeraByte is possible. If that isn't revolutionary, I don't know what is." 1 Terabyte on one plastic disc!!!!! Be still my heart... Here's the whole article.
