       I seem to recall reading of the development of the first disk drives at
IBM inSan Jose. Rather than look at control system theory and stable
feedback loops, someone figured that a vibrating head positioner could be
fixed by putting a capacitor across the actuator. After the "fix", it
shoved the head through the side of the drive.
