Zusammenfassung:A head slider moveable relative to a storage media having a storage layer is disclosed. The disc head slider comprises a read head formed on the head slider, and comprises a first electrical contact layer adapted to carry a sensor current, a second electrical contact layer adapted to carry the sensor current, a read sensor and a bias magnet. The read sensor is configured to carry the sense current perpendicular to plane. The read sensor also has a top sensor edge, and has a bottom sensor edge aligned with the air-bearing surface to access data in the storage disc. The bias magnet magnetically biases the read sensor. Further, the first and second electrical contact layers are made of a material that does not magnetically shield the read sensor.
