IT House February 22 news, my countrys scientific research team has recently made major breakthroughs in disclosure of the disc. 200 TB or 200000 GB.

This project was studied by Shanghai Institute of Technology Photon Chip ResearchAcademician Gu Min, the director of the Zhangjiang Laboratory Laboratory Calculation Office, led it. The team used the double light beam technology to break through the limit of optical diffraction limit. For the first time, it was confirmed that the information points of the information point of as many as 100 layers of three -dimensional space can be achieved.Writing and reading.
This new technology allows a single disk capacity to reach PB level, which is equivalent to at least 10,000 Blu -ray discs.In other words, driven by this technology, the number of PB CD -ROMs needed for one -year data from the world can reduce the number of two orders of magnitude compared with the hard disk, and achieve the effect of "one hundred".

According to Academician Gu Min, the PB-class three-dimensional nano-light storage technology is an epoch-making.Technology.
Taking the deep learning model GPT as an example, the data set behind it, such as the total index webpage of 5.8 billion, the size of the entire Internet text is about 56PB, if you still use 1TB capacityMoving hard disks to store these data, which is open to the area of a standard track and field.
and the three -dimensional nano -light storage developed by the scientific research team can save the storage space to a computer size, which greatly reduces economic costs.
