An air bearing slider has an air bearing surface with two rails separated by a cavity. The rails are nonsymmetrical about the longitudinal axis. Instead, the width of the active rail is greater at the trailing end than at the leading end, such as by having a hook portion 64 which extends inward at a sharp angle to the longitudinal axis of the slider. The wider hook portion 64 causes an increased flying height sensitivity to underlying disc/wind speed. The nonactive rail has a greater width than the non-hook portion of the active rail, so the slider exhibits slight negative roll. A vibration sensor is attached to the air bearing slider, and the air bearing slider is used in glide testing of discs.
