摘要： Method and apparatus for protecting a data storage device from fluid-borne contaminants. The device includes a housing in which a rotatable disc is supported, the disc having a data recording surface and an outermost perimeter. A filter assembly includes a first filter adjacent to the data recording surface and a second filter disposed beyond the outermost perimeter of the disc. During disc rotation, fluidic currents are generated and impinge a leading edge guide surface of the first filter. A first portion of the currents passes into a gap between the first filter and the data recording surface. A second portion of the currents passes along the leading edge guide surface to the second filter. The first filter is preferably characterized as a chemical adsorbent filter which adsorbs vapor phase (gaseous) contaminants, and the second filter is preferably characterized as a pass-through recirculation filter which captures particulate contaminants.

摘要： Apparatus and method for adjusting an actuator mechanical response characteristic in a data handling system, such as a disc drive. An actuator rotates about a pivot system to move a read/write head adjacent a recording surface, the pivot system comprising a stationary shaft and a bearing asesmbly comprising a stationary inner race coupled to the shaft and a rotatable outer race coupled to the actuator. A fastener is provided to engage the shaft and apply an initial amount of axially directed force on the inner race. A broad spectrum excitation is applied to the actuator and a mechanical response characteristic of the actuator is measured. The fastener is repetitively adjusted to increase the amount of axially directed force until the measured mechanical response characteristic of the actuator reaches a desired level.
