Abstract:
A magnetic device includes a write element having a write element tip and a conductive coil for carrying a current to induce a first field from the write element. A conductor proximate the write element tip carries the current to generate a second field that augments the first field. A driver provides the current to the conductive coil and the conductor, and a circuit phase shifts the current through the conductor relative to the current through the conductive coil.
