There have been a couple of posts about this lately.  I, too, have
had this happen.  I don't know if this is what is causing your
problem, but its always the cause when it happens to me.

On the underside of the floptical, there is a balck decal (sp?)
with the NeXT logo on it.  I have a disk where this decal is starting
to come off.  As it does so, it bunches up, and this causes the
drive to spit it out.  I guess the extra 2mils of thickness make
a difference.  Whenever it happens, I just press the decal back
down and all works fine.
