We designed and fabricated new flying heads with pico-sliders for cylindrical magnetic storage and evaluated read-resolution and flying height. A one-pad slider for a cylindrical medium fabricated in this study has only a small trailing pad formed on the trailing edge of the slider. We clarified the relation between the length of the trailing pad and its flying height. The envelope of the head output did not show any modulation, large spike pulse, or thermal asperity associated with contact with the cylindrical medium. The D_<50> values increased as the designed flying height decreased, i.e. as the length of trailing pad decreased. The relative flying height, derived by calculating the spacing loss factor, showed good quantitative agreement with designed flying height. The results mean that read-resolution, i.e. flying height, is improvable by appropriate design of the ABS structure of the head-slider for cylindrical media.
