Magnetic recording sliders are expected to fly at 3 to 5nm spacing above the disk in the near future. At such a small spacing, flying height modulations and intermittent contacts due to disk waviness are becoming critical issues. In previous investigations it was shown that an increase in pitch angle together with a reduction in the length of the trailing edge pad causes a reduction in spacing modulation [1][2][3]. A further improvement in spacing modulations is expected to be achieved if the disk waviness is optimized for a particular air bearing design.
