摘要：

The perpendicular magnetic recording process of a shielded-pole-type head was studied using the finite-element micromagnetic simulation. When the return and write pole are sufficiently close to each other, 40 nm in our simulation, the effective recording field is tilting at an angle of around 30 degrees. The tilted recording field leads to a more efficient writing since the recording media switching field is reduced according to Stoner-Wohlfarth model. This means that the shielded-pole-type head can be used to write higher coercivity recording media and allow for higher recording density and better thermal stability.
