Storage capacity increases with the amount of information. However, in terms of its safety for transmission to future generations, there is not many alternative, as claimed by Kadzuesi Torii , researchers at Hitachi. The life of modern magnetic and optical drives are only a few decades, and their ability to resist the negative influence from the outside is in doubt. Science offers a variety of solutions to this problem, for example , the application of a platinum pattern on a sapphire surface. But it is not particularly effective, and very expensive.
In turn, Hitachi offered as a perpetual use of drive plate made of quartz glass, which is applied to the binary code with a laser. The density of information, which is recorded in the four layers of 40 megabytes per square inch, and the thickness of plate is two millimeters. They are not sensitive to chemical reagents, and for several hours can withstand temperatures of 1000 degrees Celsius. The recorded information will be stored for as long as the glass is not broken. In the case of commercial success recorded data volume can be increased. Related Products :
