It is very evident that slowly and gradually 4.7GB DVDs are on verge of becoming outmoded. It’s not that the Blu-ray DVD comprising of a capacity of 128 GB has stolen the show; it’s just that there is a much bigger giant in the line now. You will be highly surprised to know that a team of scientists at the Swinburne University claim to have discovered a break-through method that can actually mount 1000TB of storage space onto a single DVD.
Let us explain you the exact science and technology behind the discovery of this amazing 1000TB DVD. The storage capacity of a DVD is restricted by the size of a laser beam burning the tiny pits that symbolizes the streams of data. Blu-ray increased the capacity of the disk by switching to even smaller blue lasers and therefore the storage space of the technology boosted as well. Basically the researchers worked around the law which was way back discovered that by the use of two beam lights that cancel each other out, a much smaller beam can be created to burn out the smallest pits on the disk further increasing the storage capacity massively.
There is still a lot to be done about this technology till it is made available to the consumers. It’s really mind boggling like how these amazingly small pits can actually be read after they have been formed. And since here we are talking about 1000TB of data so it seems it would take forever, plus extending faster ways to burn the disk will also become a necessity before the consumers are all ready to adapt to this new technology.
Over all we completely acknowledge how the DVDs and Blu-rays are taking such an inspiring leap in the field of storage capacity.
