Given today's disk technology this is not really

a big surprise. One way to increase the speed of

a head positioning servo is to make it open loop

for at least part of its bandwidth, relying on

controlled forces and inertia to control fast

movement rather than on position feedback. Any

such system would be quite sensitive to vibration

in the frequency range not covered by feedback.
