I'm not so sure that that is high enough for damage but it is probably
too close. I _do_ know that there is a high speed tape duplication system
that heats the media past the Curie point and then cools it in "contact"
with the media to be duplicated. As the media cools it will _easily_
align its domians with any applied field.

As for hard disk media, the material becomes magnetizable after it is cooled.
