ABSTRACT:
A magnetic device includes a write element having a write element tip and a first return element magnetically coupled to the write element on a trailing side of the write element. A conductor is positioned proximate to an edge of the write element tip and is configured to generate an assist field that augments a write field generated by the write element. A shield that includes at least one gap extends from the first return element toward the write element tip.
