SCIENTISTS have unveiled new DVD technology that stores data in five dimensions, making it possible to pack more than 2000 movies onto a single disc.
A team of researchers at the Swinburne University of Technology in Melbourne, Australia, have used nanotechnology to boost the storage potential nearly 10,000-fold compared to standard DVDs, according to a study published in the peer-reviewed journal Nature.
Discs currently have three spatial dimensions. By using gold nanorods Gu and colleagues were able to add two additional dimensions, one based on the colour spectrum, and the other on polarisation.
Because nanoparticles react to light depending on their shape, it was possible to record information in a range of different colour’s wavelengths at the same physical location on the disc.
