In thesis, we use the finite element method to calculate the
thin-film head field, to understand the recording fields of
various head with different geometric shapes, so that we could
apply a magnetic head for better performance. From the
calculation, we know that a model of bevel head have a
betterperformance in the lower flying high of y=1/8g.Also,
increasing the recording density by reduce the head width are
very limited. And, apply an external shielding can reduce the
field outside the boundary by 30% to 1%, effectively limit
therecording field to increasing the recording density.
