Five Dimensional Recording DVDs

Now you can record 1.6 terabytes of data in one single DVD type disc. Thus, you can have 300 DVDs in one single disc.

A new optical recording method could pave the way for data discs with 300 times the storage capacity of standard DVDs, Nature journal reports..... (More)

The DVD will cost just under $0.05. The technology used is that of one of the properties of gold, "nano-rods" by manipulating the light pointed at them. A group of scientist from Swinburne University of Technology Australia have developed this DVDs which exploit the property of gold to write data.

They say they were able to introduce a spectral - or colour - dimension and a polarisation dimension, as well as recording information in 10 layers of the nano-rod films, adding a third spatial dimension.
