A team of researchers from the University of Shanghai for Science and Technology in China has developed a cutting-edge data storage technique in optical discs with a capacity of up to 100TB per side. The innovative technique utilizes a 3D planar recording architecture with a transparent film capable of storing data up to 100 layers per side (current Blu-ray discs have 4 layers), totaling 0.8 petabits or 100 terabytes per side. However, the new type of optical disc (which is not officially named yet) may hold even more data, but faces challenges in creating drives to read such massive amounts of data quickly. Therefore, the research team is considering an organizational approach, using the new discs for long-term data backup, focusing on the durability of discs that can last for 50-100 years, and at a unit price cheaper than other storage methods.
