A new method of storing data using light, and salt crystals
Data storage systems are increasingly evolving every year. Back in the early 2000s, the volume of a DVD-ROM drive is quite enough for most needs. Then came the era of Blu-Ray and SSD-drives. Who is being developed in full memory based on the DNA, but scientists from Australia have suggested something new: they want to use a low-power laser and nanocrystals of salt.
For the new study responds team of three higher institutions of Australia: Experts University of South Australia, Adelaide, and the University of New South Wales. The technology is a low-power laser exposure in salt nanocrystals having fluorescent properties. With the help of certain patterns laser can transmit data and record them. According to one of the authors of Dr. Nick Risena,
"Fluorescence salt nanocrystals may be a promising alternative to conventional HDD and SSD, and Blu-Ray disks. During the experiments, we were able to create an optical structures for data storage in salt nanocrystals that are impossible to see with the naked eye. This allows for a very high density. "
In addition, the new method is a "multi-layer", ie 1 nanocrystal can store multiple bits of data, which, moreover, are rewritable. The technology enables the use of low-power lasers, which makes it accessible to consumer electronics. Using the "change of the laser patterns of behavior", scientists have been able to ensure that the laser beam can both transmit and read data, and salt nanocrystals can be embedded in plastic, glass or any other material, making them virtually any shape that makes such data carriers in the long term it is very comfortable.
