    摘要: A method for fabricating a magnetic recording transducer having a magnetic writer pole with a short effective throat height is provided. In an embodiment, a writer structure comprising a magnetic writer pole having a trailing bevel and a nonmagnetic stack on the top surface of the writer pole is provided. A dielectric write gap layer comprising alumina is deposited over the trailing bevel section and the nonmagnetic stack; and at least one etch stop layer is deposited over the dielectric write gap layer. A layer of nonmagnetic fill material is deposited over the etch stop layer and to form a nonmagnetic bevel by performing a dry etch process. The etch stop layer(s) are removed from the short throat section; and a trailing shield is deposited over the short throat section, nonmagnetic bevel, and nonmagnetic stack top surface.
