Storage systems are increasingly developing every year. In the early 2000s, the volume of DVDs is quite enough for most needs. Then came the era of Blu-Ray and SSD. Now vengeance are developing a memory based on DNA, but scientists from Australia suggested something new: they want to use a low powered laser and nanocrystals of salt.
For the new study team from three higher institutions in Australia: the experts of the universities of South Australia, Adelaide and the University of New South Wales. The technology is based on the effects of low power laser on the salt nanocrystals possessing fluorescent properties. Using specific templates, the laser can transmit data and write them. According to one of the authors Dr. nick Risen,
“Fluorescence of nanocrystals of salt can be a promising alternative to the traditional HDD and SSD, and Blu-Ray discs. During the experiments we managed to create an optical structure for storing data in nanocrystals of salt, which even cannot be seen with the naked eye. This allows for very high density recording.”
Moreover, the new method is “layered”, that is, 1 nanocrystal can store multiple bits of data, which, moreover, are writable. The technology enables the use of low power lasers, which makes it available for consumer electronics. Using “templates of behavior change laser,” scientists were able to ensure that the laser beam can transmit, and read data, and nanocrystals of salt can be embedded in plastic, glass or any other material, giving them almost any shape, making such media in the future, very convenient.
