The new
approach, which has been dubbed “five-dimensional” optical
recording, is based on colour and polarisation and uses
nanoparticles of gold as a recording medium.
These golden “nano-rods” reflect the light with different
colour and polarisations according to the angle and length
of the beam of laser light which is pointed at them. This
allows data to be recorded several times in the same place,
without interference. |
The research team estimates 1,600GB storage media the size
of a standard DVD could be on sale within five to ten years. |
