Overview

• A new technology developed in China could enable optical discs to store up to 200 terabytes of data.
• The technology, involving hundreds of layers and breaking the optical diffraction barrier, could revive optical media as a cost-effective alternative for long-term storage.
• Researchers claim the new storage medium outperforms other optical systems and hard drives in terms of areal density.
• The discs are highly stable with an expected lifespan of 50 to 100 years, offering a significant advantage over current data storage solutions.
• While the technology shows promise, improvements in writing speed and energy efficiency are needed for commercial viability.
