We know that hard drives can be stored magnetic data a decade at most.
But you can ignore most of this period? Can you Terkh these units for future generations the history of human civilizations that preceded also chronicles the history of ancient civilizations stones for us ?
Yes Vpetknologgio the new design can fabricate nano hard drive that can store data for a million years or more .
It was produced by a research team from the Netherlands disk can store data that can last a million years , Fbalrjoa for 1956 , when IBM introduced the first computer in the world and was able to store the data on the magnetic disk 305 IBM RAMAC size using fifty 24 inch unit for storing up only 5 MB, and this Alanjaza was big in those days.
But on this day , it is difficult to find hard drives that can store 1 terabyte of data on a single disc only 3.5 inches.
This poses an interesting problem. How can we keep information about human civilization and our history for the future and last longer than that? , As our forefathers did when he left the civilizations in the stone, in other words, you can store the information technology reliably for a million years or more ?
Today, we have the answer , thanks to the work of " Jeroen de Vries " at the University of Twente in the Netherlands and some of his colleagues, who were able to make the hard drive capable of storing data for future , to carry out tests " accelerated aging " , which shows that the hard drive must be able to store the data for a million years and perhaps more .
These researchers assume theories on aging, and it is clear that it is not practical to make the experience of aging in real time , especially when measured in periods ranging from millions of years. But there is a way to speed up this process , and this is based on the idea that data should be stored within the limits of earthly power and separated by energy barriers , and according to some reports that the energy barrier required is 63 or KBT KBT last 70 million years .
Single disc in pregnancy , and the data is stored in it in the pattern of lines etched into the metal disc thinning and then covered with a layer of protective equipment , the metal is tungsten , which was chosen due to the high heat resistance melts at ( 3422 ° C ) and a low coefficient of thermal expansion, the protective layer material is silicon nitride ( Si3N4) and was selected because of its high tensile strength and low coefficient of thermal expansion also .
Researchers making disc using standard etching techniques to data stored in the form of lines and QR BB large - Modkh image size and above 100 nm, is then heated to various temperatures to see how the performance of data retention in this album.
It ' s really the results are impressive . According to the law Erhenius , the disc is able to continue for a million years if I could survive for an hour when the temperature is estimated at 445 degrees Kelvin , a successful test of the new discs with ease, and in fact has able to survive at temperatures up to 848 K , and if it was with the loss of large amounts of information.
Compared to the Rosetta project proposed by the Long Now Foundation Foundation to create archival material capable of storing information for periods of more than 10 000 years , this invention is much better.
The new work suggests that we should be able to keep a lot of information about future human civilizations . Researchers and declares that they are sure they can make data storage systems much more powerful . His work exciting step toward keeping data for future civilizations
