You urban folks really know how to party Sapphire can permanently save data

Tencent digital hearing Apple's favor to allow this kind of material in the recent fire sapphire. But as the screen of electronic equipment, the super hard material there is another kind of design: data storage.

It is more difficult to save data for a long time than you think. If kept properly, paper and film can be circulated for generations. But even in the best of circumstances, they still fail. Digital storage media (CD, flash memory and hard disk) have a lifetime of up to 30 years - assuming they are not scratched, corroded, erased or replaced by new technologies. As for cloud storage, it is only in the premise that we maintain the existing Internet infrastructure is effective, and this is not what you can control.

If you want to save a data for one thousand years, one hundred thousand years or even one million years, the existing technical means can do? In response, the French entrepreneur Alain Rey and Farid Benzakour have their own solutions. They have invented a technique for etching data onto sapphire by means of a high power laser, which is said to permanently retain data.

This technique, called "Nanoform", can basically be seen as a high-tech blend of slate and microfilm slides. Compared to the ancients using tools to chisel the symbols on the stone, Rey and Benzakour used a sophisticated laser etching process to "write" the information in the laboratory on the sapphire. Because of the high degree of precision of this etching technique, we can only read the content after amplification.

In order to show the fine degree of this technology, two entrepreneurs will be the "war and peace" to print the sapphire on a disc of 4 inches, and the more than and 100 words work occupied only to the area of 1/4 disc. In addition to text etching, the technology can actually print anything you need, like a picture.

In addition to waterproof, fireproof, anti acid and anti corrosion, the data storage technology and many other advantages, such as no computer can read information will not be stolen by hackers, you can use any amplification device reading etc..

Rey and Benzakour recently brought their projects to Kickstarter to raise the money needed for production. If you spend $150 (about 931 yuan) to support this project, you can customize a piece of their own original etching disk. Assuming everything goes well, the product is expected to ship in November this year.
