Gigayear Hard Disk: Hard Disk That Can Last Up To 1 Million Years

Gigayear HardiskTypically, a standard magnetic hard disk will only be able to store data for 10 years. If your hard disk is able to last longer than that period, then it can be classified as a miracle.

To store important information that covers the whole of humanity as well as the achievements attained by mankind, such storage method is clearly very far from ideal. To answer this problem, scientists at the University of Twente developed a storage solution that is theoretically able to last longer than the human race itself: a hard disk gigayear.

Pairs of targets they do not mess around: 1 million years! Do not stop there, because this team has even set a target for the hard disk can last up to 1 billion years…

“I wonder if (achievement) that are in the form of music, art, literature literary, or scientific breakthrough, mankind always has a tendency to keep the information for future generations in the future. At some point, the human race will be extinct and all gently achievement will also participate.”

Given a pure endurance test on the hard disk is clearly not possible, then the only way is to do a simulation of accelerated testing. Of the trial, which is made of material tungsten (wolfram) and coated by silicon nitride noted promising results. Data in the form of QR code is stored in the disk is able to withstand the weather and a simulation test in theory would be able to hold up to 1 million years.

However it should be noted that the disc is able to withstand the weather factors only, while factors such as fire accident will obviously destroy the disc along with the data stored in it. During this record is securely stored , the scientists are optimistic that the data contained in it will be able to survive for a very long period of time.

If you have the hard disk gigayear, roughly what you want to say to your grandchildren?
