Hah!  You were spoiled!  Dysan is truly the BEST manufacturer of
floppy disks around.  Their manufacturing procedure differs from the
rest of the floppy disk world in one important area:  Dysan cuts the
mylar base into donuts and then applies the magnetic oxide coating in
circular tracks and buffs the disk surfaces.  Everyone else lays on
the oxide coating and buffs the disk in a cross-hatch matrix BEFORE
cutting the donuts.

It's a small difference, but Dysan has the best warranty on disks I've
ever seen, so they must be pretty sure of their process.  BTW, this
was explained to me by a factory rep from Syncom (a disk manufacturer)
about 6 years ago, when I worked in a computer store in Salt Lake City.

We sold Syncom, Maxell, and Dysan disks.  We never had a Dysan come
back, we would replace a Maxell every couple of months, and the
Syncoms worked great in Apple ][s and not at all in anything else.
The Maxells sometimes had troubles when we tried to format them on the
DEC Rainbow, which had pretty picky floppy drives.  DEC sold Dysans
with their label on them, so we sold Dysans to the Rainbow and Pro-350
owners.
