Amazing News : 300 DVDs Equal A Single Disc ??

Research workers have come up with a Modern optical recording method that could see 1.6 Terabyte - or equal 300 DVDs - matching on a single disc. It's an awsome technology.

The Researchers at Swinburne University of Technology and Science in Australia have come up with a Modern optical recording method that may allow a jumbo 1.6 TBs of data – the equal of 300 DVDs – to match on a single disc, according to Nature.
Their 5-D recording formula uses nanometer-scale particles of gold as a recording intermediate and controls the light pointed at them.

How does this work? The nanoparticles record data in different color wavelengths, all in the equal physical disk location. As the number of incoming laser light absorbed by the nanoparticles depends on its polarization, this lets the researchers to record dissimilar layers of data at different angles to make the 5-D effect.
Previous recording methods have been through polarization or color; this is the 1st for combining the two. And they tell that complicating the formula could eventually mean being able to set 10 Terabyte of data on a single disc. And then, James Chon, a co-author on the research, told the BBC: "The optical system to record and read 5-D is really similar to the current DVD system. Consequently the industrial scale production of the compact system is possible." The price of the discs to record this way are about a nickel each, but running to silver nano-rods would bring that cost down by a element of 100.
