ABSTRACT:
Methods for fabricating pole piece tips for a magnetic transducer are disclosed. The ion-milling operations for trimming P2and notching P1are controlled using feed-forward and feedback. The preferred method of the invention includes steps for setting four time values used in different phases of the ion-milling process based on feed-forward and feedback of measured values including the P2width measured in the mask, multiple P2B measurements and measurement of the notch depth.
