5D-the drives will retain data for billions of years

Scientists at the Center for the study of optics at the University of Southampton reported that they were able to improve the technology records data in five dimensions. The media not only able to survive mankind, but also to store huge amounts of information in a compact size. Data is written to stable thermal disk using ultrashort pulses of femtosecond lasers. One disk fits 360 terabytes of data, it will not get damage even at temperatures up to 1000 degrees. At room temperature the carrier material to dissolve for 13.8 billion years.
5D-the drives will retain data for billions of years
Each file consists of three layers of nanostructures, arranged in three traditional dimensions. The importance and size of the focus, so scientists use the term 5D. The nanostructures change the polarization of light passing through the disk, and data is read with a microscope and polarizer.
The technology was first demonstrated in 2013, but then scientists could fit on the disc only test file of 300 kilobits. Over the past three years the technology has improved considerably.
