Microsoft presented a proof of concept for storing data in glass.
They managed to put a movie onto a 75 x 75 x 2 millimeters thick piece of glass.
Why are they doing it?
develop solutions that are cheap enough and effortless enough that you don’t really have to make a choice about whether to store your data
How does it work?
Project Silica’s infrared lasers encode data in “voxels,” the three-dimensional equivalent of the pixels that make up a flat image. Unlike other optical storage media that write data on the surface of something, Project Silica stores data within the glass itself. A 2-mm-thick piece of glass, for instance, can contain more than 100 layers of voxels.
To read the data back, machine learning algorithms decode the patterns created when polarized light shines through the glass. Unlike tape storage – which takes time to spool to get to the place you want to read back – the algorithms can quickly zero in on any point within the glass square, potentially reducing lag time to retrieve information.
I am curious how fast will glass supersede tape for long-term storage. What do you think?
