A Million-Year Hard Disk - ScienceNOW

‎"The sapphire disk is one product of that effort. It's made from two thin disks, about 20 centimeters across, of industrial sapphire. On one side, text or images are etched in platinum—Charton says a single disk can store 40,000 miniaturized pages—and then the two disks are molecularly fused together. All a future archaeologist would need to read them is a microscope. The disks have been immersed in acid to test their durability and to simulate ageing. Charton says they hope to demonstrate a lifetime of 10 million years."

It's hard to imagine humans being around for 10 million years.

That's hella cool.
