Chinese Scientists Develop Groundbreaking Petabit-Level Optical Disk Memory

Beijing, The Gulf Observer: A pioneering three-dimensional nanoscale optical disk memory with a staggering petabit capacity has been successfully developed at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, marking a significant leap in data storage technology. The groundbreaking achievement was reported in an article published on Thursday in the prestigious journal Nature.

The research team, led by experts at the Shanghai Institute of Optics and Fine Mechanics, achieved the petabit-level capacity by elevating the planar recording architecture to three dimensions, incorporating hundreds of layers. This innovative approach not only significantly increased the storage capacity but also surpassed the optical diffraction limit barrier of the recorded spots. The minimum spot size and lateral track pitch were achieved at an impressive 54 nm and 70 nm, respectively.

The optical recording medium developed by the team is based on a photoresist film doped with an aggregation-induced emission dye, which can be optically stimulated by femtosecond laser beams. This cutting-edge technology represents the world’s first successful realization of a petabit-level capacity optical disk.

The research findings are poised to revolutionize the capabilities of archival data storage in data centers. The breakthrough addresses challenges in large-capacity and energy-efficient storage technology, opening new avenues for advancements in data management and archival storage. The petabit-level optical disk memory showcases the relentless pursuit of innovation by Chinese scientists in the field of nanotechnology and data storage.
