Patent ID: 7903378

Claim:
A magnetic head structure comprising a recording element comprising: a main magnetic pole layer; and a recording-side monitor element to be used as an element resistance monitor in polishing for forming a medium-facing surface of the recording element, the recording-side monitor element including: a resistance film, the resistance film being U-shaped in two-dimensions, a lead conductor located as a layer below the resistance film, the lead conductor comprising a first lead conductor part and a second lead conductor part separated from the first lead conductor part, and a contact conductor comprising a first contact conductor part and a second contact conductor part, the first contact conductor part connecting the resistance film and the first lead conductor part, the second contact conductor part connecting the resistance film and the second lead conductor part, wherein the resistance film is composed of the same material as that for a lowermost layer of the main magnetic pole layer or a base layer, the base layer being arranged beneath the main magnetic pole layer, and where the resistance film is disposed on the same plane as that for the lowermost layer or the base layer, in such a way as to straddle the surface position of a medium-facing surface to be regulated by the polishing in the height direction, and the contact conductor and the lead conductor are disposed while being retreated to the back side of the surface position of the medium-facing surface to be regulated by the polishing in the height direction, wherein the magnetic pole layer is formed on the base layer, and wherein the base layer is formed from the same material as the material for the resistance film.
