Abstract
Approaches for a magnetic write head having a stacked coil architecture. Embodiments utilize the better process control capability available with thin films' thicknesses, compared to the control capability of vertical gap-filling processes, which provides for better scalability to shorter yoke length magnetic write heads, which are faster at writing data bits than are magnetic write heads having a longer yoke length.
