An inductive-type write head and its method of fabrication are disclosed. The
write head has a vertically separated two-element planar coil of reduced resistance
which is the result of forming the lower of the two coils with windings of a greater
height and substantially larger cross-sectional area than those of the upper coil.
The formation of a lower coil with greater height is possible because of a surface
planarization that allows separating the coils by an alumina layer of minimal thickness.
This method allows the reduction of coil resistance without the necessity of enlarging
the head dimensions. The reduced resistance results in lower power consumption
and the elimination of pole tip protrusion caused by excessive heating during operation.
