Abstract: Disclosed herein are embodiments of sliders in which the length of the slider is less than or equal to its width. Also disclosed are data storage devices (e.g., hard disk drives) comprising such sliders. The sliders may include one or more air-bearing surface features to compensate for the lower aspect ratio and to meet performance targets (fly height, roll stiffness, etc.). Such features may include, for example, a trading-edge pad (which may include an efficiency -flattening hole), a first cavity between a first side of the trading-edge pad and a first side edge, and a non-intersecting second cavity between a second side of the trailing -edge pad and a second side edge. A slider may also or alternatively include a leading pad and, in some embodiments, a particle trapping structure between the leading pad and the slider's leading edge.
