Abstract
A sub-ambient pressure air bearing slider is configured with longitudinal air-bearing rails that have angular side recesses near the trailing end of the slider. Sub-ambient pressure regions formed within the side recesses during disk operation oppose the asymmetrical lift forces which cause undesirable roll. The slider provides improved roll and flying height characteristics.
