Patent ID: 7495864

Claim:
A perpendicular magnetic recording head comprising: a first coil layer that has a plurality of first coil pieces which extend in a track width direction and are placed in a direction crossing the track width having a predetermined intervals in between; a second coil layer that has a plurality of second coil pieces which extend in the track width direction and are formed in a direction crossing the track width having a predetermined intervals in between, the second coil layer being formed above the first coil layer; contact layers each of which electrically connects the first coil layer to the second coil layer; and a laminator that has a main magnetic pole layer and a gap layer which are formed between the first coil layer and the second coil layer and above a region between the contact layers, wherein first insulating layers are formed at both sides of the laminator, a second insulating layer is formed on a region ranging from a top surface of the laminator to top surfaces of the first insulating layers and below the second coil layer, an inclined surface and a flat surface that is continuous to the inclined surface are formed in each of the first insulating layers, the inclined surface being inclined downward when progressing toward a lateral direction, in the second insulating layer, each of the inclined surfaces inclined downward when progressing toward the lateral direction is formed on the inclined surface of the first insulating layer, and a lateral region of the second coil layer extends downward along each of the inclined surfaces of the second insulating layers, and an inclined angle θ 1 of the inclined surface of the first insulating layer with respect to the flat surface is larger than an inclined angle θ 2 of the inclined surface of the second insulating layer with respect to the flat surface.
