We studied a magnetic recording head for a cylindrical perpendicular magnetic storage system with regard to its stability when a slider is flying over a rotating 1-inch-diameter cylindrical medium. We also designed an inclined-pad-type slider for the cylindrical magnetic storage system. This slider has an inclined pad formed on its leading edge and a trailing pad formed on its trailing edge, to generate an air-bearing force. The inclined pad is protruded in the thickness direction of the slider relative to the trailing pad. A waveform of an acoustic-emission (AE) sensor and an envelope of a reproduced signal were obtained from the combination of the cylindrical perpendicular medium and fabricated this slider. These waveforms did not show any large pulse and thermal asperity associated with contact. These results confirm the flying stability of the inclined-pad-type slider.
