Abstract
Disclosed herein are sliders with particle-trapping structures for trapping particles that could otherwise adversely affect the performance of a data storage device, and data storage devices comprising such sliders. A slider includes a leading edge, a trailing edge, a leading-edge structure located between the leading edge and the trailing edge, a vertical structure located between the leading-edge structure and the trailing edge, and a particle-trapping structure adjacent to the base of the vertical structure. The vertical structure has a leading-edge-facing surface, a side-edge-facing surface, and a base at a first level of an air-bearing surface (ABS) of the slider. The particle-trapping structure has a first portion adjacent to the leading-edge-facing surface and a second portion adjacent to the side-edge-facing surface. The particle-trapping structure comprises at least one cavity extending below the first level when the ABS is oriented upward.
