Their invention will speed up the development of the Internet through a giant expansion of hard drive capacity
About sensational research results the scientific world learned of the publication in the Journal of the American Physical Society Physical Review Letters. The article describes how teachers of the Ural State University (USU), Alexander Ovchinnikov, Igor Proskurin and their colleague from the Kyushu Institute of Technology Yunisiro Chisinau came close to creating technology that allows almost infinite increase the capacity of hard disk drives.
In an interview with "News" project leader 41-year-old candidate of physical and mathematical sciences, Alexander Ovchinnikov said that work on increasing disk capacity was several years: "We have been able to discover and explain the anomalies in the flow of electric current in some magnetic materials, in view of increased resistance. An infinite number of these anomalies. " Given that most of the storage and recording information on memory disks based on the mechanism of resistance changes in the external magnetic field of the magnet, this discovery provides a new look at traditional hard drives.
— Most modern devices are based on the principle of the valve, that is locking the magnetic field of the current — explains the thought process Ovchinnikov group of scientists. — When, say, from one piece of material, electrons move to another due to the fact that we apply a magnetic field, we can either allow them to flow, or not. But it is quite rude device that allows for only a binary scheme — either there or there is no signal. And we had predicted a more subtle effect: if the current will flow through the spiral-shaped magnets, due to the fact that the magnetic field is quite tricky affects the spiral, we can implement a sequence of electrical states, and fix it in whole numbers. As a result, the amount of information stored in the device is expected to grow exponentially (very rapidly and with great force — "Proceedings")
Dean of the Faculty of Physics USU Alex Granny in an interview with "News" said that the publication of Phisical Review Letters tantamount to recognition of scientists from the scientific community all over the world.
— These theoretical developments widest range of applications, — he stressed.
Director of IT-company "Corinth" Andrew Sozykin believes that first addresses the introduction of new technologies will be the server hard drives for data centers (Data Center): "There’s more of a need for storage of data, particularly in the development of cloud computing, where user data is not stored computer and data center servers. "
Sozykin believes that the opening of Ovchinnikov accelerate the development of the Internet, accelerating the already huge and exponentially growing amount of data on the web. Currently, it is estimated that on servers connected to the World Wide Web, has accumulated 487 exabytes of data (487 billion GB). This is equivalent to 19 billion-filled optical disc Blu-ray. According to analysts’ estimates, over one and a half years of data will grow twice. This whole array of information requires new methods of storage.
As for the adaptation of new technology for desktops, laptops and other mobile devices, for the introduction of new technology in these devices will require a lot of engineering solutions to optimize energy consumption, experts say. Accordingly, in the invention of each house will not so soon.
Alexander Ovchinnikov told "Izvestia" that his developments are already showing interest in the business community in Japan.
— There are already prototypes, working on the principles laid down by us, but to the mass production business will not soon — he said.
The fact is that there is not yet a standard equipment based on nanotechnology that can cost-effectively produce such systems, he says.
However, the rate of implementation of the Ovchinnikov’s not worried.
— My mission — to formulate a theory and prove its viability. Commercial implementation — this is not my field — he says.
For the Ural scientist is not the first recognition. In 2005, work Ovchinnikov "Stable nonlinear excitations of spiral type in two-dimensional magnetic models" was awarded the Prize of the governor of Sverdlovsk region.
