The black anti-halation backing was the "problem" spot, not the magnetic strip.  Since the magnetic strip had to be applied BEFORE the anti-halation backing and the backing could not go over the magnetic strip they had to use a different, heavier backing, more like paint, and the solvent needed to remove it was not good for several reasons.
