Actively synchronizing magnetic responses of a shield and a write pole

Abstract

In an example, a method of manufacturing a transducer head comprises configuring a control circuit to actively synchronize magnetic responses of a shield and a write pole during operation. The method also comprises configuring the control circuit to energize at least one coil wire during operation with a current direction opposite to current flow in a main transducer head coil. In another example, a method comprises actively synchronizing magnetic responses of a shield and a write pole. In another example, a transducer head comprises a write pole and a shield, and a control circuit actively synchronizes magnetic responses of the shield and the write pole.
