Abstract
The surface of a slider for a magnetic recording head, a burnishing head, or a glide head includes a pair of rails that, in operation, face the magnetic recording medium to form air bearing surfaces. These air bearing surfaces have slots cut into them at the same prescribed angle relative to the longitudinal axis of the slider, and along a single straight line. This provides slots which are asymmetric about the longitudinal axis, causing the slider to fly nearer the recording medium and at almost constant height.
