摘要： 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.

摘要： A magnetic shield may be capable of enhancing magnetic writing, particularly in transducing elements accessing data bits from data tracks. At least one magnetic shield is adjacent a write pole. The shield has a flux concentration feature on an air bearing surface (ABS) capable of enhancing magnetic undershoot between the shield and the write pole.
