Israeli storage developer Mempile has announced it has successfully demonstrated its new optical storage technology dubbed TeradDisc, which may offer the capability to store as much as 1 TB of data on a single DVD-sized disc.
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.
