Disc drive assembly having side rail-channeled air bearing for ramp load-unload applications Patent uri icon


  • A disc drive assembly includes a housing, a disc, an actuator, a ramp and a slider. The ramp is positioned along an edge of the disc to engage a portion of the actuator when the actuator is in a parked position. The slider is supported over the disc by the actuator and includes first and second elongated rails. Each rail has a leading bearing surface, a trailing bearing surface, and a recessed area extending between the leading and trailing bearing surfaces. First and second convergent channels are recessed within the trailing bearing surfaces of the first and second rails, respectively. Each channel includes a leading channel end open to fluid flow from the respective recessed area, non-divergent channel side walls and a trailing channel end closed to the fluid flow and forward of a localized region of the respective trailing bearing surface.
