摘要： A data reader may have a magnetoresistive stack positioned on an air bearing surface and consisting of at least a magnetically free structure that continuously extends from the air bearing surface with a first stripe height. A side shield can be separated from the magnetoresistive stack on the ABS and configured with a first magnetic layer having the first stripe height and a second magnetic layer having a third stripe height from the air bearing surface with the third stripe height being greater than the first stripe height. The side shield can be anti-ferromagnetically biased by a synthetic antiferromagnetic top shield structure that contacts the side shield through a transition metal material layer. The first stripe height can be configured to match a magnetically free layer of the magnetoresistive stack and the second stripe height can be configured to match a magnetically fixed layer of the magnetoresistive stack.
