[kvdnjiez] Longevity of magnetization

Magnetostratiography demonstrates that under certain conditions, magnetization can persist for a very long time, millions if not billions of years, much longer than (say) paper or engraving onto stone.  This might be good news for magnetic data storage if the medium is sufficiently sturdy, e.g., metal hard drive platters.

Design magnetic storage with a goal of extreme long term data storage.  The data must not rely critically on firmware or other special data hardcoded into the hard drive circuit board.
