The Birth of “Super Optical Disc” my country Has Made Breakthroughs in the Field of Optical Storage. The research team used the world's first dual-beam controlled concentration-induced luminescence super-resolution optical storage technology.
This is the first time in the world that ultra-large-capacity optical storage of the Pb level has been achieved. After accelerated aging testing, the optical disk media has a lifespan of more than 40 years, and the fluorescence contrast ratio is still as high as 20.5:1.
