Information storage 2
Where we store huge volumes of data produced today? The pieces of glass, which can withstand almost infinite.
The problem of keeping safe, long-time data is one thorny because, despite the current performance of storage media, however exustă danger of damaging it, so the loss of a large amount of valuable information. The latest progress in this field is due Hitachi, who invented a new storage medium, with exceptional performance.
The invention is based on the glass; indeed, a special glass called quartz glass, made of high purity silica. This material is very resistant to high temperatures and other environmental condiţiii difficult, so it can last without decay, a very long time - almost endlessly.
By comparison, during "life" storage media commonly used today - CDs and hard drives - is limited to a few decades or a century at most.
The new technology developed by Hitachi provides storage of binary data by creating, by means of a laser, the points inside a thin plate of quartz glass, the information can be read using an optical microsocop usually connected to a computer equipped with a special software.
As long as there is a computer that can "understand" this binary code - something that computers will become no matter how sophisticated, can be programmed to do - the data will be accessed.
Quartz glass chips are resistant to many chemicals, is not affected by radio waves, by the action of water and can withstand high temperatures up to 1000 degrees Celsius and even direct contact with the flame for at least two hours, without suffering damage.
With such properties, chips can remain functional in the event of natural disasters, such as fires or tsunamis. As long as the glass is broken, the data will survive.
For the time being, the chips have four layers of points can register 40 MB of data over an area of 6.5 cm2, about the same density as seen from a music CD. But the inventors claim that there is a problem adding more layers of points taken with laser, thus increasing storage capacity.
Success revolutionary IBM managed to store a bit of information in C12!

Researchers from IBM recently announced the creation of a microscopic size data units that you will revolutionize communication and data storage in the near future. A regular computer stores a bit of information about one million atoms. IBM researchers were able to store a bit in just 12 atoms!
The new device is likely to pave the way for a new class of nanomaterials used for memory chips and memory disks.
This will open a new era of computing and computer structure. New nanomaterials Voar have qualities superior to those of silicon components that are ubiquitous in computer components today. In addition, nanomaterials in question will open new lines of research in quantum computing.
