How to get them to you intact is another question. I
don't trust shipping
magnetics anymore.
Envolve them in aluminium paper :)
Umm, no. Aluminum has a relative permeability > 1, so wrapping the disks
in aluminum will make them a tiny bit _more_ susceptible. You'd want to
wrap them in a superconductor, or faling that a very thick layer of
bismuth :-) Practically speaking, you should just put the disks securely
Or a mu-metal box?
More seriously, I've just had 33 3.5" disks sent to me. They were
formated for an HP9114 drive, but otherwise blank. They all arrived
format-intact. I copied some data to them and sent them back, AFAIK, all
of the marrived back perfectly readable.
Of course this was not irreplacable data, so if something had gone wrong,
al lthat would have been lost would be my time for copying them. But it
shows you can send magnetic media nad have it arrive undamaged.
Oh yes, I did no special packaging. Just a few layers of bubblewrap and a
strong carboard box. No magnetic shielding.
[I guess this was classic computer related, the data I wrote ot the
disks were images of the 33 known HP calculator user club swapdisks]
