Abstract
Disclosed herein are sliders having air-bearing surface (ABS) designs to mitigate the effects of smear on near-field transducers used in data storage devices, and data storage devices comprising such sliders. A slider comprises a leading edge, a trailing edge, a NFT, and an ABS with features to increase oxygen concentration near the NFT. The ABS comprises a channel configured to direct gas in a direction from the leading edge toward the trailing edge and a funnel region connected to the channel, disposed between the channel and the NFT, and configured to receive gas from the channel. In an ABS view of the slider, a width of the funnel region along a longitudinal axis passing through the NFT monotonically increases with distance from the NFT.
