Abstract
A slider for developing an air bearing atop a spinning data disk includes a substrate having a base surface and an air bearing pad extending outwardly therefrom. The bearing pad cooperates with the spinning disk to develop the air bearing thereon for supporting the slider thereabove. A data access element is fixedly mounted in the substrate for communicating data with the disk and, a guard strip extends outwardly from the base surface and is spaced from the bearing pad to define a trench therebetween. The guard strip shields the bearing pad from debris accumulation during operation.
