discs has been designed which can
provide storage capacity of 2000 times
that of current DVDs could be just
around the corner, thanks to researchers
who have created them using nanotechnology
to store information in various colors.
According to researchers these discs
have been made by using Nanotechnology
which enables the creation of "Five
Dimensional discs" with huge
"We were able to show how nanostructured
material can be incorporated onto
a disc in order to increase data capacity,
without increasing the physical size
of the disc," lead researcher
Prof Min GU said.
Discs currently have three spatial
dimensions, but using nanoparticles
the researchers were able to introduce
a spectral -- or color -- dimension
as well as a polarization dimension.
"These extra dimensions are the
key to creating ultra-high capacity
discs," GU said.
And Gold nanorods are being inserted
into the disc to create the color
The researchers have recorded the
information in a range of different
color wavelengths’ on the same
physical disc location when the nanoparticles
are induced to light according to
