Future Data Storage Technologies You Must Know Scientists at the University of Southampton, England, have achieved a major step forward in the creation of digital data storage that is capable of surviving for billions of years. Using nanostructured glass, researchers from the University’s Optoelectronics Research Centre (ORC) have developed the recording and retrieval processes of five dimensional (5D) digital data by femtosecond laser writing.
The storage allows unprecedented properties including 360 terabytes (TB) per disc capacity, thermal stability up to 1,000°C and a virtually unlimited lifetime at room temperature (or 13.8 billion years at 190°C), opening a new era of eternal data archiving. As an extremely stable and safe form of portable memory, the technology could be highly useful in organisations with big archives, such as national archives, museums and libraries, to ensure their information and records are kept perfectly preserved.
The technology was first experimentally demonstrated in July 2013, when a simple 300 kb text file was recorded in 5D. Now, major documents from throughout human history – such as the Universal Declaration of Human Rights, Newton’s Opticks, Magna Carta and Kings James Bible – have been saved as digital copies that could survive the human race.
