Abstract
Disclosed herein are sliders that include segmented structures for trapping particles while providing adequate airflow to meet pitch stability objectives. A slider includes a vertical structure and a segmented structure disposed adjacent to the base of the vertical structure. The segmented structure comprises a plurality of particle-trapping segments and at least one gap, where each pair of two consecutive particle-trapping segments is separated by a gap. When the slider ABS faces upward, each gap is at a level that is higher than the floors of the particle-trapping segments on either side of the gap. In some embodiments, the segmented structure includes at least three particle-trapping segments and at least two gaps. In some embodiments, the lengths of the particle trapping segments account for at least eighty percent of the overall length of the segmented structure.
