摘要: A read sensor for use in a magnetic read head includes a magnetoresistive stack having a plurality of layers, and first and second shield regions positioned adjacent to the magnetoresistive stack. Each of the shield regions includes a first soft magnetic layer for shunting flux from an adjacent track to the shield region instead of the magnetoresistive stack.

摘要: Side-reading of an abutted-junction magnetic transducer is measured by constructing at least one microtrack having a transition density. The transducer is moved relative to the microtrack to identify a plurality of positions of the transducer relative to the microtrack where the transducer provides a predetermined response. The side-reading distance of the transducer is identified from the plurality of positions. In one embodiment, a plurality of microtracks are constructed during different iterations, each having a different transition density, and the positions of the transducer are identified during each iteration relative to the respective microtrack. In another embodiment, the selected transition density has a fundamental frequency, and the position of the transducer is identified relative to the microtrack where the transducer provides the predetermined response at each of a plurality of harmonic frequencies of the fundamental frequency.
