New Optical Disc Can Store Information “for a billion years”
If you’ve been worried about how to preserve your digital records, you may soon be able to purchase a new optical disk that could store data for up to a billion years. To some this may seem hubristic, to others definitely not.
According to the latest gizmag report, a researcher at the University of Twente in the Netherlands has developed a new optical memory device made out of tungsten and silicon nitride that could store data for extremely long periods of time—up to a billion years.
