Abstract: Described are magnetic recording heads that include an air-bearing surface and that are designed to be useful or potentially useful in two or more different types of fluid atmospheres; also described are related methods of testing the magnetic recording heads and installing the magnetic recording heads in a hard disk drive, as well as hard disk drives that contain a magnetic recording head as described.

Abstract: Active pressure in the air bearing surface of a slider in the region of the transducer is reduced by introducing two channels in the center pad of the advanced air bearing along each side of the centerline and spaced apart from the transducer. This configuration moves the high pressure region away from the transducer zone at the trailing edge of the slider.

Abstract: A data storage device may be configured with a transducing head mounted to a slider. The slider may be suspended above a magnetic data storage medium and have a variable depth region, central rail wall, first wall, and trailing edge wall. The variable depth region continuously contacting a central rail wall from a first wall to a trailing edge wall.
