Glass that stores vast data: ultrafast lasers encode 2 million books for 10,000 years
Microsoft Research's Silica demonstrates writing data into ordinary glass using ultrafast femtosecond laser pulses, creating voxel-based 5D memory with densities up to 1.59 gigabits per cubic millimetre and a palm-sized block capable of storing about two million books, with data lifetimes exceeding 10,000 years.
