A nonmagnetic gap covering the main pole is provided. A portion of the nonmagnetic gap resides on the top of the main pole. A first seed layer is provided. At least a portion of the first seed layer covers the portion of the nonmagnetic gap on top of the main pole. A portion of the nonmagnetic gap on the magnetic recording transducer is removed after the first seed layer is provided. A second seed layer is provided after the portion of the nonmagnetic gap is removed. The second seed layer covers at least the portion of the first seed layer. A wrap-around shield layer is provided on the second seed layer.
