Abstract: A write pole may be formed by first depositing a dielectric layer onto a substrate and then patterning the dielectric layer to form a trench with a write pole shape. The trench is subsequently filled with the evaporation deposition of a magnetic material to form a write pole. The trench may have a greater depth dimension than width dimension.

Abstract translation: 可以通过首先将介电层沉积到衬底上，然后对介电层进行构图以形成具有写极形状的沟槽来形成写入极。 随后填充有磁性材料的蒸发沉积以形成写入极。 沟槽可以具有比宽度尺寸更大的深度尺寸。
