I seem to recall that heating a magnetic material above its Curie point will _totally_ randomize the fields. If so, the next question is "is the Curie point for a floppy (or tape) high enough to damage the media?" If the answer is no, then I can see the labels now... "to declassify, place media in 350 degree oven for two hours" :-) :-) -- Leonard Erickson ...!tektronix!reed!percival!bucket!leonard CIS: [70465,203] "I used to be a hacker.
