Technology.am (May 21, 2009) — A new DVD technology makes it possible to store over 2,000 movies onto a single disc.
Australian Researchers at the Swinburne University of Technology unveiled a new DVD technology that stores data in five dimensions.
Researchers used nanotechnology to boost the storage potential nearly 10,000-fold compared to standard DVDs. They were able to demonstrate how nanostructured material can be incorporated onto a disc in order to increase data capacity, without increasing the physical size of the disc.
They said 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.
Discs currently have three spatial dimensions and it record in a single colour wavelength using a laser.
Using gold nanorods Gu and adding two additional dimensions, one based on the colour spectrum, and the other on polarization, the fifth dimension was made possible by polarisation. When light waves were projected onto the disc, the direction of the electric field within the waves aligned with the gold nanorods.
The polarisation can be rotated 360 degrees. They were, for example, able to record at zero degree polarisation. Then on top of that, were able to record another layer of information at 90 degrees polarisation, without them interfering with each other.
They have signed an agreement with Korea-based Samsung, one of the world’s largest electronics manufacturers.
