Your entire DVD collection will arrive from the fifth dimension
It sounds like utter nonsense spouted by boffins to keep the fat grants rolling in; researchers have created a DVD-style disc that stores information in five dimensions, that could increase storage by 10,000 times. It's one more step towards encapsulating the entire experience of humanity on a multi-region DVD to sell in the 4 for £20 offer at HMV.
The brains at Swinburne University of Technology in Australia say the multi-dimensional technique they've achieved allows a single normal-sized disc to store 1.6 terrabytes of data, and that within ten years that figures could reach 10 TB. Just one terrabyte is enough storage to 300 movies, so this sort of technology would transform database archiving.
The science involves nanoparticles, nanorods and plasmons, which all sound like a lot of billy bullshitters talking, but is apparently genuine parlance. In layman's terms, they've used the three standard spatial dimensions but created additional dimensions to layer data on top without creating interference - a spectral as well as a polarisation dimension - so information can be recorded at different colour wavelengths and different polaristations, over and over the same spot.
