Abstract

Disclosed are sliders for data storage devices, and data storage devices incorporating such sliders. A slider comprises a leading edge and an air-bearing surface (ABS). The ABS comprises a trailing end comprising a trailing pad, and a plurality of channels configured to direct gas in a direction from the leading edge toward the trailing end, wherein each of the plurality of channels is connected to the trailing end. The plurality of channels may include a center channel, an inner-diameter channel, and/or an outer-diameter channel. The disclosed sliders may be particularly advantageous for lower-pressure operating environments, such as sealed-helium disk drives.
