Unsurprisingly, the majority of floppy disk magnetic media was/is made
by the leaders in audio magnetic media.  The two historic giants in that
field were BASF and 3M, who independently invented magnetic recording
technology.
Personally, my favorite floppy brand is Verbatim DataLife Plus.  They
use a Teflon media coating and are virtually indestructible in normal
usage.  If you spilled something on one, you just cut the side of the
jacket, pulled out the media, washed it in warm soapy water, put it back
in another jacket and you were good to go.

 Subject:       Floppy Disk Media
 Just curious here, does anyone have a list of the MANY brands of
 floppy
 disks and who the actual manufacturer might be?  I got intrigued
 several
 years ago with the many floppy disks that were available and have been
 just setting them aside as I saw interesting ones.  So far, I haven't
 bothered to catalog them but it is interesting to see the different
 jackets.
