Today, many prominent scientists are developing revolutionary data recording technologies, there have even been attempts use DNA as a carrier. However, all this remains under development. In fact, we see only theoretical calculations without even specifying the timing for the implementation of all these ideas in practice, not to mention the commercialization of one or another project.
In this series of inventions, technology is most profitable, proposed by Russian scientists at Kazan University. The thing is the fact that the Russians did not take the basis of revolutionary development some exotic media, and already used optical discs – DVD or BluRay, which even by modern standards is significantly inferior to hard drives, flash memory and other drives.
Yes, a modern optical disc is very limited in volume recordings that can be placed on it with the help of light (laser) – this is the diffraction limit (the laser beam can only focus on the groove is half the length of the light – approximately 400 nm for BluRay).
So Russian scientists have found a way to truly fantastic density of such a recording – using an antenna nano size and azobenzene base for recording. If you don’t go into subtleties of this technology, such light recording overcomes limitations of the diffraction limit, and therefore the recording density will be almost forty times higher than the most advanced modern hard drives and a million times higher than modern optical carriers.
Thanks to this revolutionary development on a square decimeter A disc (DVD size) can record one petabyte of data. TO in a word let’s say that today Google processes no more than 24 petabytes of data per day, that is, all this a tremendous amount of data can fit almost all two dozen optical discs.
Moreover, Kazan scientists promise that new optical discs will not be as susceptible to mechanical damage as modern DVD and BluRau, therefore, it is possible, we will become witnessing a return to optical computers and laptops recording-reading devices, though they will, of course, a completely different format.
