Abstract

A data reader generally capable of sensing data bits may be configured at least with a magnetic stack that has free and fixed magnetization structures atop a magnetic seed layer. A bottom shield may be positioned contactingly adjacent the magnetic stack opposite a top shield with the bottom shield having a fixed pinning magnetization set to a predetermined magnetic orientation.
