With negative pressure sliders having step bearings, there are variations in flying height resulting from variations in shape factors, such as the step bearing depth. In order to achieve lower flying height, it is considered necessary to reduce the variation in flying height caused by the variation in curvature of the air bearing surface and the variation in flying height caused by the variation in the shapes of the step bearings. The curvature of the air bearing surface of the slider can be observed in the pre-cut row bar condition or in a unit product condition. Shape data of the magnetic head slider can be input, such as the step bearing depth, etc., so as to calculate the predicted flying height of the slider An arithmetic processing unit calculates an adjusted target curvature from the difference between the predicted flying height and the target flying height.
