Abstract
A magnetic head comprises a pole layer, a first coil, a second coil, and a shield. The shield incorporates: a first portion located backward of the pole layer along the direction of travel of a recording medium; a second portion located forward of the pole layer along the direction of travel of the recording medium; and two coupling portions. The first portion has an end face located in a medium facing surface. The two coupling portions couple the first and second portions to each other without touching the pole layer. Part of the first coil passes through a space surrounded by the pole layer and the first portion. Part of the second coil passes through a space surrounded by the pole layer and the second portion.
