Microsoft’s Project Silica demonstrates that digital data can be stored in ordinary borosilicate glass for over 10,000 years. Using femtosecond lasers, researchers encode information as microscopic 3D voxels, achieving densities of 4.8 terabytes on a 2mm sheet. Unlike magnetic tapes or hard drives that degrade within decades, glass resists heat, moisture, and dust. …Microsoft’s Project Silica demonstrates that digital data can be stored in ordinary borosilicate glass for over 10,000 years.
