Abstract:
1. A method for screening a magnetic-recording head for use as a manufacturing-qualified, magnetic-recording head utilizing a simulated-cross-track-gain profile of said magnetic-recording head, said method comprising: measuring a track profile of said magnetic-recording head; providing said simulated-cross-track-gain profile of said magnetic-recording head synthesized utilizing said track profile of said magnetic-recording head; calculating a peak-to-peak value of said simulated-cross-track-gain profile; applying a selection criterion based on said peak-to-peak value of said simulated-cross-track-gain profile to screen said magnetic-recording head for use as said manufacturing-qualified, magnetic-recording head, wherein providing said simulated-cross-track-gain profile of said magnetic-recording head further comprises: wherein applying said selection criterion further comprises:
