Also, it's most likely not magnetic. ;-)

<p>Plus, both probably aren't heavy in iron oxide.</p>
<p>But, on the disk side, wasn't Fe2O3 used for awhile on disk
platters? I imagine they changed at some point, but finding
details on when and to what are not turning up in 5 minutes of
googling. A paper from 2003 talks about Nitrogenated and
hydrogenated amorphous carbon films, but I think they are talking
about a protective layer over the magnetic material. Wikipedia
says something about a cobalt based alloy, but I can't find
anything definite beyond that, and when I go looking for Cobalt
alloys, they mostly seem to be cobalt and iron and other stuff.
If the other stuff includes oxygen, I suspect that would mean it
was still fair to call it ferrous oxide.<br>
