A Game Changer? 125TB Optical Discs on the Horizon
Chinese researchers have unveiled a breakthrough in data storage: a 125TB optical disc. This innovation, detailed in Nature's "A 3D nanoscale optical disk memory with petabit capacity," utilizes a novel material called AIE-DDPR.
AIE-DDPR boasts exceptional storage density and boasts a lifespan of 50-100 years, potentially reducing reliance on cloud storage and data migration. Additionally, its manufacturing process is similar to traditional CDs and DVDs, making it potentially cost-effective.
The researchers describe the technology: "We develop an optical recording medium based on a photoresist film doped with aggregation-induced emission dye, which can be optically stimulated by femtosecond laser beams. This film is highly transparent and uniform, and the aggregation-induced emission phenomenon provides the storage mechanism. It can also be inhibited by another deactivating beam, resulting in a recording spot with a super-resolution scale."
