Abstract
Disclosed herein are sliders with segmented front bars, methods of manufacturing them, and data storage devices comprising them. In some embodiments, a slider comprises a segmented front bar, a leading pad, a shallow-edge surface, and a cavity. The segmented front bar includes a plurality of slots situated substantially perpendicular to the leading-edge surface of the slider. The leading pad is situated between the leading-edge surface of the slider and a trailing edge of the slider and is recessed from the segmented front bar. The cavity abuts the segmented front bar and is situated between the segmented front bar and the leading pad. The shallow-etch surface is situated between the cavity and the leading pad. A maximum depth of the plurality of slots relative to a non-recessed surface of the segmented front bar is less than a depth of the cavity relative to the non-recessed surface of the segmented front bar.
