Patent ID: 7119976

Claim:
A magnetic head comprising: a nonmagnetic substrate; at least one servo read head disposed on a transducing surface of the substrate, said servo read head comprising: first and second trenches on the transducing surface, said trenches having side portions and a bottom portion; a first magnetic layer on the side and bottom portions of the first and second trenches; a first insulation layer on the first magnetic layer; a conductive coil having at least one turn on the first insulation layer in the first and second trenches; a second insulation layer on the conductive coil and the first insulation layer in the first and second trenches; a second magnetic layer on the second insulation layer in the first trench, said second magnetic layer in contact with the first magnetic layer at the side portions of the first trench forming a magnetic yoke enclosing the at least one turn of the conductive coil in the first trench; and wherein the second magnetic layer has a read gap at the transducing surface; and an overlayer on the second magnetic layer and the transducing surface.
