5D ‘Superman memory crystal’ heralds unlimited lifetime data storage

Data written to a glass “memory crystal” could remain intact for a million years, according to scientists from the UK and the Netherlands who have demonstrated the technology for the first time. The data-storage technique uses a laser to alter the optical properties of fused quartz at the nanoscale. The researchers say it has the potential to store a staggering 360 terabytes of data (equivalent to 75,000 DVDs) on a standard-sized disc.

The researchers claim that their memory crystals “[open] the era of unlimited lifetime data storage.” As well as providing unprecedented capacity and high-speed reading, fused quartz is exceptionally stable and can withstand temperatures up to 1000 °C. “We think it should potentially last a million years,” enthuses Zhang, meaning the stored data will likely outlast the human race.
