Researchers at the University of Southampton in the UK successfully stored the entirety of the human genome sequence onto an indestructible 5D optical memory crystal no bigger than a penny. The indestructibility claims are no joke since the discs can withstand temperatures up to 1,000°C, cosmic radiation, and even direct impact forces of 10 tons per cm2.
Nice. We need something like this. Digital archiving is still best done on magnetic tape as disk and flash drives all fail after a few decades. But even for regular users, it’d be nice to keep a digital copy of family photos that lasts forever.
As someone who works in a digital archives, let me tell you that the honest to god problem with old tape is that you have to find an old tape reader (drive) that works. Tape from those old IBM reals still works if its not exposed to the elements. But like the modern LTO stuff, finding a reader for that old stuff is the challenge.
A steady hand, and a magnetised needle: and feel the data in your heart, as your hand trembles to the tape’s expression.
