Abstract:
In some embodiments, a magnetic reader comprises first and second shields extending from an air bearing surface (ABS), a magnetoresistive stack is located between the first and second shields, and a flux guide is separated from the magnetoresistive stack while connecting the first and second shields. The flux guide magnetically couples the distal end of the magnetoresistive stack to the first shield.
