Hard Drive Storage
Hard drive storage capacity increases strongly, but the speed at which evidence is written has reach its limits. Researchers from The Aydhenhoven University of Technology and FOM present a promising new technology that may allow data to stored a thousand times faster. This technique, where ultra-short laser oscillations exist and are used to generate a vector current, also opens the way for future optical computing chips.
Hard drives store data in the form of microscopic magnetic fields, as magnetic field directions — north or south — called magnetization determine whether the data is 0 or 1. information is stored by changing the rules of magnetic fields for several interconnected pieces. A dedicated disk writing head exists used to create local magnetic fields. Which, in turn, changes the direction of the bit*.
Local Magnetic Field And The Speed Of Conversion Storage
The relationship between the intensity of the local magnetic field and the speed of conversion between directions and thus the conversion from zero or single values is an ejection relationship where the more robust the magnetic field. The greater the conversion speed between the different values and therefore the higher the storage speed. The obstacle that this technique has certain limits cannot exist exceeded and has already existed maximized in this technique.
“The number of bits has grown dramatically and very rapidly in recent years. As oppose to the speed at which data is store. Which has grown with difficulty. Therefore, there is an urgent need for new technology in data storage,” says the Professor Eindhoven University of Technology.
For example, physicists have exploited an essential property in electrons called spin, an internal compass in the electron. Using high-speed laser pulses, they generated a flow of electrons in a particular material so that all electrons had the same direction as the tuber.
The result was a vector current or Spin current that changes the material’s magnetic properties. This new technology has resulted in a change in magnetization is less than 100 parts of 1,000 million seconds of Femto sec, 1,000 times faster than the maximum capacity of the technology used these days.
In addition, the researchers were able to describe the physical process done in detail as it existed and discussed whether the current spin generating was capable of causing a change in the magnet or not. It has existed proven that this current is already capable of doing so.
Other Information about Storage
in addition, this new property can move several steps forward in the future of optical computer chips. Which researchers are currently working on. A dutch grant of €20 million has existed granted to integrate photonics with computer systems. Which enables this new technology to store optical data in magnetic bits. That offers excellent opportunities to use light as a carrier of information.
It is the primary and smallest unit in the computer. And digital systems operate either zero (no electrical pulse) or one (electric pulse).
