Method of making a PMR writer with seamless shields
Abstract:
A process (and the structure resulting therefrom) is described for manufacturing a magnetic write head in which there is no physical interface between the first and second trailing shields. This is achieved by laying down a sacrificial layer which is patterned to extend inwards towards the top yoke whereby the dimensions and shapes of the shields are defined.
