How lasers etch data into quartz

Our entire digital history—from photos to scientific breakthroughs—is stored on hard drives that will decay in a matter of decades. Are we walking into a digital dark age? This video reveals the groundbreaking technology of 5D optical data storage. Researchers are using ultra-fast femtosecond lasers to etch information directly into the molecular structure of pure quartz glass, creating an indestructible hard drive. We explain how data is encoded in five dimensions—using the 3D position, size, and orientation of nanoscale deformations called voxels. A piece of glass the size of a coaster can hold hundreds of terabytes. Impervious to extreme heat, radiation, and the passage of time, this "Superman memory crystal" can preserve human knowledge for billions of years without needing a single drop of electricity. If you are fascinated by the future of computing and how we will preserve our legacy, this one's for you.
