TDK has developed a prototype optical disc that can hold up to 320GB of information -- that's more than six times the current highest-capacity media available. The 12-centimeter disc has 10 recording layers, each of which can store 32 Gigabytes. In comparison a Blu-ray Disc can hold 25GB on each layer, and a dual-layer disc is the highest capacity generally available at present. This is a great achievement! What do you guys think?
TDK made a 200GB Blu-ray disc over 3 years ago, so it's really not *that* impressive and not like we are going to see it any time soon. http://www.eweek.com/c/a/Data-Storage/TDK-Reveals-Prototype-of-200GB-Bluray-Disc/
