Dozens of gigabytes of data can now be encoded on a virtually indestructible glass hard drive that’s the size and shape of a drink coaster.
Microsoft just revealed a proof of concept.
It’s a thin square of glass that’s been laser-etched with microscopic geometric shapes called “voxels” that contain a combined 75.6 gigabytes of data, which contains the 1978 film Superman in its entirety.
The announcement is a publicity stunt, sure, but the idea of storing our most important data on slices of glass is undeniably poignant – and practical.
This week’s announcement happened in partnership with Warner Bros., the major Hollywood movie studio that produced said Superman movie.
According to the company’s press release, these little glass coasters could help Warner Bros. transition its archives from vulnerable 35-millimetre film onto a medium that could last centuries.
