A writer portion of a recording head is disclosed. The writer portion includes a lower magnetic pole. An oxide gap is positioned on the lower magnetic pole. A first insulating layer is positioned on a first portion of the gap oxide, the first insulator layer having a planarized top surface. A plurality of intermediate insulating layers are positioned on top of the first insulating layer. Each intermediate insulating layer encapsulates a layer of conductive coils and has a planarized top surface. A last insulating layer is positioned on top of a portion of the plurality of intermediate insulating layers and on top of a second portion of the gap oxide. An upper magnetic pole is positioned on top of the last insulating layer and on top of a third portion of the gap oxide.
