  • Patent number: 7633719
    Abstract: An apparatus which provides improved positional control for an access element moveable adjacent a rotatable surface, such as a data transducing head adjacent a data recording disc in a data storage device. The apparatus comprises a fluidic stripper with one or more cantilevered arms which project proximate a corresponding array of one or more rotatable surfaces. Each arm comprises an edge surface which extends proximate to and in facing relationship with a movement path of an access element across the associated rotatable surface to impede fluidic currents established by rotation of the rotatable surface. Each arm further supports a ramp structure which receivingly supports the access element at a position away from the rotatable surface and proximate the innermost diameter during a deactivated mode when the rotatable surface is stationary.
