Abstract
The relationship of the track profile in MR heads to the magnetic state of the MR sensor is studied in two examples. The first, using an exchange bias film for transverse biasing, was chosen because it displays a range of track profile behavior. The second employs soft film biasing. Using a detailed micromagnetic model, the quiescent bias states and track profiles were computed, and the formation of the track profile analyzed in terms of the magnetic response of the MR sensor; The anisotropic propagation of signal flux in the magnetic films of the sensor was seen to have a strong affect
