A method and apparatus for providing a three step air bearing with
improved fly height performance is disclosed. The slider includes a
funnel structure for directing air flow to a predetermined location
toward a trailing edge of the slider and a collection structure for
gathering air flow at the predetermined location. The slider is formed
using three etch depths. A crossrail and side rails may be provided. The
elements of the slider form five negative pressure areas to provide
improved air bearing stiffness and minimize fly height sigma performance.
The collection structure includes angled sides and the side rails further
include trailing ABS side angles, wherein the trailing ABS side angles
and the angled sides of the collection structure directing air flow
around the collection structure to prevent contamination buildup.
