  • Abstract
    Testing of film heads while still on the substrate is important in determining those heads suitable for processing through fabrication of air bearings, mounting on suspensions and final testing. A proper interpretation of on-substrate test results is essential. This paper analyzes the relationship between head inductances measured on the substrate and poletip width, magnetic permeabilities, film thicknesses and planar dimensions.
