Abstract: A method includes receiving an image of a surface of a slider bar from an interferometer, where the slider bar includes at least two sliders, and where the image includes image data according to at least two image data channels for a slider bar surface and the at least two sliders. The method also includes generating a slider bar map of the surface of the slider bar based upon the image data of the image, where the slider bar map includes at least two data channels and ascertaining a plurality of individual slider surface maps based on a number of sliders included on the slider bar, where the ascertaining is also based upon the slider bar map having the at least two data channels. The method also includes segmenting the slider bar map according to the plurality of individual slider surface maps.

Abstract: A data writer may suspend a transducing head from an actuator. The transducing head can consist of a writer coil positioned proximal a write pole. A protruding signal may be passed through the write coil to contact a data storage medium with the transducing head. A write signal can be passed through the write coil to write a data bit on the data storage medium.

Abstract: A slider that minimizes lubricant accumulation includes bearing surfaces that provide above ambient fluid pressure, a cavity located between two bearing surfaces and at least one step feature that is spaced apart from the bearing surfaces and is located in and protrudes from a floor of the cavity at a height that is less than a height of the bearing surfaces. The at least one step feature includes surfaces configured to diverge and converge airflow in the cavity.
