Anonymous Howard writes: Have you heard of Mempile? I haven't, but this company based out of Israel have gone on the record stating that they are working on a 1TB optical disc that is the same size as a standard DVD disc. They key here is that they have actually demonstrated the optical disc, dubbed TeraDisc, successfully, so it's not just vaporware. Mempile says it is using non-linear two-photon technology to read and record data in over 100 transparent "virtual" layers which take up the entire volume of a disc. The approach is radically different from conventional blue-laser technology like Blu-ray and HD DVD, in which partial reflection from multiple layers significantly reduces signal while increasing background noise and interference. Mempile's technology, conversely, can handle over 100 layers wile providing true WORM capabilities and bit-by-bit recording and addressing. The best part: Mempile recently demonstrated the technology to Japanese consumer electronics manufacturers and they were reported as being "amazed". Could this be the beginning of the end of the Blu-ray and HD-DVD format wars?
