Patent ID: 7206168

Claim:
A thin-film magnetic head, comprising: a lower core layer extending from a surface of the thin-film magnetic head opposed to a recording medium in a height direction; a magnetic upper core layer extending above and away from the lower core layer by a predetermined distance, the magnetic upper core layer coupled to the lower core layer on a rear side in the height direction; a toroidal coil layer comprising a plurality of first coil pieces disposed below the magnetic upper core layer and a plurality of second coil pieces disposed above the magnetic upper core layer, the first and second coil pieces being wound around the magnetic upper core layer, wherein each of the plurality of first coil pieces is electrically connected in a track-width direction to a corresponding second coil piece; and a lead layer, the lead layer connected to the toroidal coil layer and supplying a recording current thereto, wherein a rearmost first or second coil piece lying furthest from the opposing surface in the height direction has a larger width in a width direction and a larger area than other coil pieces corresponding to said rearmost first or second coil piece, the rearmost first or second coil piece comprising two connecting portions, a first connecting portion connectively opposed to one of the other corresponding coil pieces in the film-thickness direction, and a second connecting portion connected to the lead layer; and wherein the first and second connecting portions are formed near a front end side of the rearmost first or second coil piece closest to the surface opposed to the recording medium.
