IBM told Nature that it is possible to get as much information as possible in an increasingly smaller space and that is exactly what you are looking for in the world of computing, where impressive results have already been achieved. Still, everything we know or predicted for the future in this area can be much more surprising.
And that’s how IBM discovered a way to store and read data on a single atom.
This study recently published by IBM researchers describes how it was possible to store data and later read them from a single atom.
Nothing more than a bit, that was the amount of information added to an atom, and nowadays a common hard disk is capable of storing the same amount of information in a hundred thousand atoms.
This discovery means, therefore, theoretically, that in the future, hard disks similar in size to the existing credit cards, capable of storing, for example, 35 million songs or even the entire iTunes catalog can be manufactured.
But the truth is that it will be slow, expensive and inadequate to the present day.
Although this is a breakthrough that opens the door to the future of storing a huge amount of data in a very small space, the reality of the facts is that this process is completely inadequate to what is expected today.
All this technique involved is extremely expensive, since it requires an electronic microscope, developed by IBM, that has to be cooled with liquid nitrogen and only works in a vacuum, and not only is reading and writing very slow.
But the most important idea that is drawn from this study is that it is possible to store information in a single atom and that, in the future, it is certain that we will have atomic hard disks.
