Quartz glass can preserve data for millions of years

Researchers in Japan have come up with a novel way to store data — in a wafer of quartz glass — that could preserve it for eons.

Electronics company Hitachi says this process protects the information in a durable, waterproof covering that could weather hundreds of millions of years with almost no degradation.

Researchers created a prototype using pieces of quartz glass developed by Kyoto University — measuring two centimetres square and just two millimetres thick.

Inside this square wafer are four different layers with binary-based dots inlaid by pulses of light. The dots are information in binary form and can be read with a laser-based reader scanner or a basic optical microscope.

Since those layers are embossed, erosion does not affect them.
