Abstract
A method of manufacturing a thin film magnetic head which employs pole tips members which are coplanar in a plane across the write gap to produce a written track whose width is determined by the thickness of the pole tip members. The coplanar write structure may be-combined with a multilayer read sensor disposed in the write gap to produce a narrow trackwidth thin film magnetic head having both write and read capabilities.
