Researchers at Shanghai College of Science and Know-how have developed an optical compact disc (CD) that may retailer about 1.6 petabits, or 200 terabytes, of data on either side. The article was revealed within the scientific journal Nature, Day.Az stories with regards to Gazeta.ru.
For comparability, a contemporary Blue-ray disc means that you can retailer about 100 gigabytes of knowledge. Thus, a brand new disc can change 2 thousand Blue-ray discs.
Scientists have managed to considerably improve the capability of optical disks by the structure of planar 3D recording. The expertise makes use of a extremely clear, homogeneous photoresist movie, which is coated with a particular dye that reacts to femtosecond lasers. This made it attainable to pack a whole bunch of layers into an area that beforehand held as much as 4 layers.
In accordance with the researchers, one other benefit of their growth was sturdiness – petabit disks can final from 50 to 100 years.
The authors consider that their discovery will make knowledge facilities rather more compact, decreasing warmth and power consumption. As well as, the brand new drives will give individuals again the power to retailer giant quantities of worthwhile info at residence with out counting on the cloud. Nevertheless, widespread adoption of petabit disks just isn’t but attainable as a result of lack of obtainable gadgets for taking part in them.
