IT Home reported on February 22 that China's scientific research team has recently made a major breakthrough in optical disc storageThe new format can record 100 layers on each side of the disc for a total capacity of 16 petabits, equivalent to 200 TB or 200,000 GB.
Source: University of Shanghai for Science and Technology*** The project is led by Academician Gu Min, Dean of the Institute of Photonic Chips of the University of Shanghai for Science and Technology and Director of the Institute of Optical Computing of Zhangjiang Laboratory.
This new technology allows a single disc to be capacities up to petabytes, which is equivalent to the capacity of at least 10,000 Blu-ray discs. In other words, driven by this technology, the number of petabyte-level optical discs needed to store a year's worth of global data can be reduced by two orders of magnitude compared to hard disks, achieving the effect of "one to hundred".
Source: **According to Academician Gu Min, the petabyte-level massive 3D nanophoton storage technology is an epoch-making technology.
Taking the deep learning model GPT as an example, the dataset behind it, such as the total number of indexed web pages is as high as 5.8 billion, and the text size of the entire Internet is about 56 petabytes.
The 3D nanophotonic storage developed by the research team can save storage space to the size of a computer, which greatly reduces the economic cost.
