Abstract:
The first and second side surfaces of either a bottom spin valve sensor or a top spin valve sensor are notched so as to enable a reduction in the magnetoresistive coefficient of side portions of the sensor beyond the track width region thereby minimizing side reading by the sensor. The first and second notches of the spin valve sensor are then filled with layers in various embodiments of the invention to complete the spin valve sensor.
