Using servo data harmonics to monitor head-medium spacing

A method is disclosed that includes measuring a first amplitude and a second amplitude in a servo pattern signal derived from a transducer head interacting with a medium; and providing an indication of a change in a spacing distance between the head and the medium, wherein the change in the spacing...
