Memory longevity is a touchy subject that most businesses, researchers, and consumers purposefully ignore. Magnetic drives, in theory, are thought to be corrupted in about 40 years due to the Earth’s magnetic field, though this has not been fully observed yet (hard drives have only seen widespread since the 80s). Optical discs, such as CDs and DVDs are expected to become corrupt in about 30-100 years, if not kept out of contact with moisture and oxygen. So if we wanted to store something for more than a century, there are few good current solutions. Until now, that is; Japanese researchers have come up with a new form of ultra-long term memory that they say can last over 1,000 years. They dub their memory the Digital Rosetta Stone, or DRS memory for short.
