As per estimation, the data produced by humans per a day is around 10 million Blu-ray discs. For this huge data to be stored there is a need of storage place in the form of some storage device. To solve the problem of storing huge amounts of data for long time the UK researchers have invented this tiny glass disc or can be correctly said “a five dimensional (5D) digital data disc that can store 360 terabytes of data for 13.8 billion years”.
Technology behind
Researchers at Optoelectronics Research Center (ORC) in the University of Southampton devised a revolutionary way to record and retrieve five dimensional (5D) data on a nanostructured glass disc using femtosecond lasers.
Information was stored on the disc using ultrafast lasers, which produced intense yet very short light pulses. The digital 1’s and 0’s on the disc in nanostructured dots.
This technology is referred to as “Superman memory crystal”.
Storage capacity and capability
The properties of the glass disc allow to store up to 360 TB of digital data and can withstand extreme temperatures of up to 1,000 degree Celsius (equivalent to 1,832 degrees Fahrenheit).
The disc can store the data up to 13.8 billion years, if stored at room temperatures of up to 190 degrees Celsius (374 degrees Fahrenheit).
According to the researchers, the technology offers a safe and stable form of memory storage that can be used to store large volumes of information for various organizations such as libraries, museums and national archives.
A professor at Optoelectronics Research Center, Peter Kazansky said “This technology can secure the last evidence of our civilization: all we’ve learnt will not be forgotten.”
