Abstract: A data reader can be configured with at least a magnetoresistive stack contacting one or more magnetic shields. The magnetoresistive stack can be separated from a magnetic shield by a seed lamination on an air bearing surface with the seed lamination consisting of at least three sub-layers that are constructed with different material compositions.
