Chinese researchers have developed a high-density molecular storage system that uses organic molecules to store and encrypt data, reports Blocks & Files. Information is recorded and retrieved using a specialized atomic force microscope, which manipulates molecular states to store data, according to the description at Nature. While the technology can potentially enable ultra-high-density storage devices that reduce storage space requirements and power consumption (e.g., HDDs with capacities of 100TB and higher), short lifespan of atomic microscope tips remains a major obstacle.
