Ill be gone for a bit as well, btw, data CAN be burned. The simple explanation: data is essentially either stored in a cloud, network, or metal. Data is magnetic codes, put into a network, cloud, or metal. This can be destroyed by:
1. Physical damage(bumping or dropping the object)
2. Manipulation through an anisotropic material.
3. Achieving the curie temperature
4.very poor intrinsic coercive force
5. Expanding past the magnetic saturation
6. Going past the maximum operating temperature
7. Exposure to residual magnetism
8. An extreme change in the magnet's gradient.
9. The eventual flip in the earth's magnetic flux in a million years or so, ending up destroying magnetic materials and leaving no protection from solar radiation, thus leading to our extinction.(in that case dont worry about burning data, worry about cancer and the breakdown of your cells, one by one, leading to one of the most immense pains you can possibly feel.)
That wraps up what I know about burning materials. If you want more info, search da google. Have a nice trip!
