Abstract
A magnetic head having precisely controlled MR height has a slider substrate and a magnetic head part provided on the slider substrate. The magnetic head part includes, seeing from a medium-opposing surface side, a magnetism detecting element; an upper magnetic shield layer arranged on the magnetism detecting element; an electrode layer separated in a track width direction from the upper magnetic shield layer; and a conductor layer, arranged closer to the slider substrate than are the upper magnetic shield layer and electrode layer, extending in the track width direction so as to be in contact with the upper magnetic shield layer and electrode layer and forming a part of the medium-opposing surface.
