Chinese researchers have developed a 'Super DVD' disc with hundreds of layers, increasing its capacity to 1.6 petabits, equivalent to approximately 200 terabytes. This breakthrough in optical data storage technology has the potential to revolutionize archiving and large data centers, as it could hold thousands of 4K feature-length movies on a single disc, while physical media offerings are on the decline.
Scientists have developed a "super DVD" capable of holding a petabit of information, equivalent to approximately 125,000 gigabytes or nearly a quarter-million regular DVDs. This breakthrough in optical data storage involves printing information in 3D across hundreds of layers, surpassing the optical diffraction limit barrier. Aside from its potential environmental benefits, the super DVD offers the convenience of having an extensive collection of content readily available on a single disc, blurring the lines between physical media and streaming.
Chinese researchers have developed a new optical disk format with a capacity of up to 125TB, achieved through nanotechnology and a 3D stacking architecture. The disks are designed for long-term archival data storage, with a claimed shelf life of 50 to 100 years, and are said to be highly stable with no special storage requirements. The research team is working on improving data transfer speeds, lowering write energy, and making the disks more affordable for commercialization.
