  • Advanced air bearing slider
    Patent number: 10796721
    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.

  • High passive stiffness and low active pressure air bearing feature
    Patent number: 10586563
    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.
