The present disclosure is generally related to a magnetic media drive employing a magnetic recording head. The magnetic recording head comprises a main pole and a wrap-around shield surrounding at least two sides of the main pole at a media facing surface. The wrap-around shield comprises an electroplated, laminated NiFeX film, where X is one of Re, Cr, or Ir. The NiFeX film comprises about 1 atomic percent to about 12 atomic percent of X, about 30 atomic percent to about 50 atomic percent of Ni, and balance of Fe. The NiFeX film comprises a plurality of layers, each layer comprising a first sublayer having a Re content of about 1 atomic percent to about 43 atomic percent and a second sublayer having a Re content of about 0 atomic percent to about 12 atomic percent. The NiFeX film increases the damping constant of the magnetic recording head.
