I'd assumed it was the coercivity that was differnt, but mayne it's the 
remanence. I will admit I've not done any measurement :-).

I am pretty sure that audio cassetes (even with a notch cut in them) do 
not work well in ECMA34 tape drives. And that the data tapes make lousy 
audio tapes at any normal bias setting.
