Abstract:
An apparatus, system, and method are disclosed for the cancellation of repeatable runout signals. A signal processing module receives a position error signal and outputs a position compensated signal. A feed forward module receives the position error signal and outputs one or more cancellation signals to cancel one or more repeatable runout components from the position error signal when combined with the position compensated signal. A combining module combines the position compensated signal and the cancellation signals into a position command signal. A feedback module receives the position command signal and outputs the position error signal.
