俄羅斯研發永久光碟 能儲存資料100萬年

Russian scientists are completing work on super-stable optical memory technology to create a disc capable of storing information for one million years under certain conditions.

俄羅斯科學家即將完成超級穩定的光儲存技術的研發工作，以創造一種在特定條件下能將資料儲存100萬年的光碟。

They created a prototype of an "eternal disc" and will conduct research and development work in 2018-2020, said Ivan Glebov, head of the Moscow-based laboratory of laser nanostructuring in glass at the Foundation for Advanced Research Projects.

位於莫斯科的先進研究專案基金會鐳射奈米結構玻璃實驗室主任伊萬·格列博夫表示，他們製造出了“永久光碟”的原型，並將在2018-2020年開展研發工作。

The new storage device is made of quartz glass. To record data, a femtosecond laser delivers extremely short and intense light pulses onto a piece of quartz.

這種新型儲存裝置由石英玻璃製成。飛秒鐳射器將極短且強的光脈衝傳送到一片石英上以燒錄資料。

The disc is resistant to fires, radiation and electromagnetic waves.

該光碟耐火、防輻射還防電磁波。

It will be capable of storing up to 1 TB of data in the future. Presently, the researchers are striving for 25 GB/disc data capacity.

未來，該光碟將可儲存高達1TB的資料。目前，研究人員力爭使每個光碟的資料容量達到25GB。

At the current stage, the FARP laboratory regards state organizations, such as the Book Chamber and the Russian State Library, as the first users of the new technology.

在現階段，先進研究專案基金會實驗室把諸如版本圖書館和俄羅斯國家圖書館在內的國家性機構，作為該技術的第一批使用者。

"The technology also attracts organizations that need long-term or permanent data storage. There are a lot of such organizations, and it is especially important to data processing centers, because they accumulate a large volume of information from various state structures," Glebov said.

格列博夫稱：“該技術還吸引了需要長期或永久資料儲存的機構。有很多這樣的組織，而對於資料處理中心來說這尤其重要，因為這樣它們就可以從不同的國家機構中積累大量的資訊。”
