Engineers at Swinburne University Of Technology have developed an optical computing technology that would allow storing of about 10.6 years of HD-TV video on a single disc aka nearly a petabyte (=1048576 GB) of data on a single disc. Professor Min Gu, the diretor for micro-photonics at Swinburne said that the technology now allows us to produce a focal spot that is about 1 / 10,000 th of the human hair. It allows more data to be written on the overall writeable area of the disc. The breakthrough technique developed by Prof. Gu and his team mates Zongsong Gan and Dr. Yaoyu Cao allows 3-D optical beam lithography at nine nanometers. Just to put it into proper reference, the head of a pin is about a million nanometers!
Essentially, the team has overcome a fundamental law o optical science, discovered in 1873 by scientist Ernst Abbe, that the light beam focused by a lens cannot produce a focal spot smaller than half of the wavelength or 500 nm for visible light.
While this law allowed development of modern microscopy and became an indispensable tool in physics, chemistry, material and biological sciences; it created barrier for the scientists to access small structures which are just a few nanometers wide. Professor Gu says that optical beam lithography is the ultimate approach to 3D fabrication at the nano level. The details of the research can be obtained from Swinburne official page: #-Link-Snipped-#
We've seen how the research engineers are working on development of next generation of storage systems for the ever growing data storage needs. It's estimated that the total amount of data generated by the world doubles every two years - and we are soon going to be in the dire need of better storage system. The petabyte class, disk based storage systems could open entirely new frontiers for storing information on optical media - something that's taken a backseat in the last few months with the emergence of cloud storage system.
We however are quite excited by the idea of storing truckloads of our photos and videos on a single physical disc. What about you?
