Sound like a batch of tapes with slurry issues. I have run across this one a few occasions. Usually the shedding has been pretty light, with most of the oxide coming from the edges. I've never experienced flaking with these tapes, though-just some light shedding. Richard Hess will probably have some better info. Scott D.
