Spindle filter in a data recording disk file |
摘要 |
A filtering means is provided in a data recording disk file for filtering air flowing from the region of the spindle bearings into the head/disk area of the disk file. The filtering means is mounted to the disk file frame adjacent the rotary shaft of the spindle and together with the shaft defines a narrow annular gap for the flow of a very small portion of the total air flow from the region surrounding the spindle bearings. The filtering means includes first and second ring members which have axially-directed openings and which together support filter material located between the ring members. The primary portion of the air flow from the spindle bearings passes through the axially-directed openings of the ring members and the filter material and is thus filtered before entering the head/disk area. The filtering means also serves as a make-up filter for those generally sealed disk files in which the rotating disks serve as a pumping means for recirculating air within the head/disk area and in which the region surrounding the drive motor is open to the atmosphere.
