A slider that moves a transducer across a surface of a rotating storage disk includes an island that protrudes from a surface of a subambient pressure cavity for supporting the transducer, the island having length and width dimensions that are less than those of the slider. A groove is positioned at the forward end of at least one of the side rails that define the cavity to allow air to flow between the cavity and an area outside of said cavity. The groove serves to maintain the distance between the surface of that rail and the disk surface equal to the distance between the surface of the other rail and the disk surface as the slider moves across the disk. The rail includes a plurality of grooves for equalizing the flying heights of the rails; a first one of the grooves intersects the cavity to allow air to flow between the cavity and an area outside of the slider, while and a second one of the grooves is spaced from the cavity by a portion of the rail.
A slider for moving a transducer across a surface of a rotating storage disk while maintaining the transducer in proximity to and spaced from the disk surface, said slider having a cavity for developing a subambient pressure as the disk rotates that tends to draw said slider toward the disk surface, said cavity being bounded by portions of said slider that are raised from a lower surface opposing said storage disk, said slider comprising
