      • Surface profiling, or the inspection of microscopic surface features on media
        Surface profiling, or the inspection of microscopic surface features on media, measures such details as pole-tip recession and air-bearing surface flatness. Early on, profilers dragged a stylus across the surface of the media, but that destroyed the sample; improvements on that design used lower-force tips to measure the surface, but still damaged enough sliders that profilers remained consigned to the laboratory. However, the advent of atomic force microscopy brought about the first noncontact
