How many movies would you physically own if the following events happened? leave the world behind Would it ever come true? If the answer is about 14,000 or less, he may soon need only one optical disc to store them.
Scientists at Shanghai University of Science and Technology have developed a new “3D nanoscale optical disc” that is the same size and shape as a DVD or Blu-ray disc, but can store a staggering 1.6 petabits of data, according to a report. did. Charles Q. Choi, IEEE Spectrum. How much data is that in terms most people understand? That’s about 200,000 GB, which is the space required for 14,285 two-hour 4K movies, assuming each movie is 14 GB in size. will be almost the same.
The research team’s findings were published in the journal Nature.
The secret to the new disk’s capacity lies in its 3D storage system. Instead of writing data to one layer, use 100 layers. The individual “spots” of data are also much smaller than on traditional Blu-rays and DVDs. “Data is recorded using a spot as small as 54 nanometers wide, which is about one-tenth the wavelength of visible light used to read and write data,” says Choi.
This new recording technology is made possible by the use of dual data writing lasers and a newly developed photosensitive material called AIE-DDPR.
What’s even more remarkable is that scientists have announced that one new blank disc can be produced in less than six minutes using traditional DVD mass production techniques.
Despite the clear potential for 8K movies as a physical format, given that interest in disc-based movies is rapidly declining, the chances of this new technology making its way into our homes remain uncertain. would be low. The team believes the real opportunity lies in the data center. By using nanoscale optical disks, data centers will be able to store exabit information within her one room. This is an amount of data that currently requires space the size of a stadium.
