摘要

A write head incorporates a bottom pole layer and a top pole layer that include pole portions, and a write gap layer disposed between the pole portion of the bottom pole layer and the pole portion of the top pole layer. The write head further incorporates a thin-film coil at least a part of which is located between the bottom pole layer and the top pole layer and insulated from these pole layers. Each of the bottom pole layer and the top pole layer includes a pole portion layer and a yoke portion layer. An end of each of the yoke portion layers facing toward an air bearing surface is located at a distance from the air bearing surface.
