ABSTRACT:
The structure for a closely spaced, coplanar tape head array is disclosed. Narrow pitch is obtained by utilizing an overlapping coil structure, wherein write coils of adjacent heads overlap. The overlap is made possible by placing coils of adjacent heads at different levels within the thin film structure, separated by dielectric insulating layers.
