摘要：

Nonlinear finite element calculations show that the soft underlayer thickness in perpendicular media can be greatly reduced without significant loss of effective switching field strength by using a shielded pole writer in place of the more conventional monopole geometry. In addition, use of a thin soft underlayer (SUL) with a shielded pole writer with a thin SUL results in a higher gradient and a narrower magnetic write width. These results have been qualitatively confirmed experimentally. (c) 2005 American Institute of Physics.
