Researchers from Shanghai University of Science and Technology have developed an optical disk that can hold 200 TB of information. That's 40 000 times the capacity of a regular DVD. Techcult.ru reports this.
The properties of the new product are based on three factors:
special photosensitive material: AIE-DDPR, developed through decades of research, permits data to be stored on 100 layers of disk.
ultra-precise encoding technology: The “spots” for recording information on each layer are only 54 nanometers in size, which ensures dense data packaging.
nanometer laser: Provides precise synchronization of data read and write on a multilayer structure.
The production of such media is possible on standard equipment, and the production time of one copy is only 6 minutes.
While it's unlikely that such drives will be available in retail stores, they could revolutionize the way data centers store data. Compact optical disks AIE-DDPR compare favorably with traditional HDDs in size, and from SSDs in capacity.
