Method and system for actively controlling and reducing induced electrostatic voltage on a magnetic storage disk

Actively controlling ESI voltage on an object such as a magnetic storage disk, a rotating MR head, or insulator, includes the method and system for actively monitoring a generated ESI voltage on the object. The method and system generate (, and ) a signal responsive to the generated ESI voltage. Then, an opposing ESI voltage is produced from the responsive signal. The method and system then apply the opposing ESI voltage to the object for opposing and controlling the generated ESI voltage.
