Last month, GE revealed that its research scientists had discovered a way, using holographic technology, to store 100 DVDs worth of information on a single standard DVD. What a difference a few weeks make.
In what can only be seen as a "serving" (or pwning) of the GE researchers, the B-Boys researchers at the Swinburne University of Technology in Melbourne, Australia, have gone way past 100 and on to 2,000.
While standard DVDs are made with three spatial dimensions, the Aussie researchers added two more.
Using nanoparticles--extremely small bits of matter--the Swinburne team was able to introduce a spectral (or color) dimension and a polarization dimension.
To create the "color dimension," the researchers inserted gold nanorods onto a disc's surface. Because nanoparticles react to light according to their shape, this allowed the researchers to record information in a range of different color wavelengths on the same physical disc location. Their findings appear in the current issue of the scientific journal Nature.
Current DVDs are recorded in a single color wavelength using a laser. Brain explode yet? No? Well just keep reading, pal. … Read more
