Forward-looking: As consumers increasingly turn toward digital distribution and data center operators try various storage methods, optical discs haven’t stopped evolving. A recently published paper explains how manufacturers could make DVD-like discs that hold the equivalent of hundreds or thousands of Blu-rays.
Researchers at the University of Shanghai for Science and Technology have developed an optical disc with a capacity of over a petabit of data, equivalent to well over 100 terabytes. Although the technology is primarily proposed for enterprise use, it could potentially become accessible to consumers after overcoming significant obstacles.
The scientists were able to significantly increase the capacity of an optical disc by implementing a 3D planar recording architecture. The technology uses a highly transparent, uniform photoresist film doped with aggregation-induced emission dye and stimulated by femtosecond lasers.
