A groundbreaking study from Chinese scientists reveals a revolutionary optical disc, the size of a DVD, capable of storing over 1 million gigabits, transcending the limitations of traditional two-dimensional data storage. The innovation involves encoding data in three dimensions on 100 layers of optical discs, setting a new standard for data density.
Traditional optical discs, such as CDs and DVDs, encode data using microscopic pits representing binary code. Prior attempts to increase their capacity involved multiple layers, but the size limitations of optics hindered progress. The Chinese researchers overcame this challenge by developing a disc with 100 layers, utilizing spots as small as 54 nanometers, a significant advancement over the wavelengths of visible light.
