Microsoft encodes data as hundreds of layers of laser-etched voxels inside 2mm-thick borosilicate glass, using machine learning models to read it back
Microsoft's Project Silica has written 4.8 terabytes of data into a 2mm-thick sheet of borosilicate glass using femtosecond lasers, encoding it as 301 layers of 3D voxels that machine learning models read back — and accelerated ageing tests suggest the data will still be intact in 10,000 years.
