摘要:
An apparatus includes a write pole magnetically coupled to write coils that generate a first magnetic field during a switching event. The apparatus includes a shield at a media-facing surface and proximate the write pole. A conductive element is disposed proximate the shield and configured to generate a second magnetic field opposite to the first magnetic field during the switching event. A selected one of the write coils is located adjacent the shield separate from others of the write coils.
