There's nothing to add, it is, resp. seems to be, brutal truth ... 90°C
might be the correct value or not, anyway, the most unsafe way to backup
data is an optical media. There's no better guarantee to loose data. If
magnetic saved date should fail, well, this would be much more bad luck.
Hm, you might watch my DAT drives "eating" the DAT tapes?!
DVD-RAM and HDD IMO are the most safe opinions :(.
