Vapor Drain - Recirculation Filter

      Disclosed is a Vapor Drain-Recirculation Filter which adsorbs
organic outgases generated in HDD inside, by an activation carbon
sheet (Kynol) inserted into a recirculation filter.

      The Figure shows the example of this device.  A Kynol filter
(ACC507-15) of 15x5 mm is contained into a recirculation filter made
of polypropyrene sheet.  The recirculation filter containing a Kynol
filter is set into DE, as shown in the Figure.  When a hard disk
rotates, the recirculation filter itself catches small particles by
air flowing and simultaneously the Kynol filter in the recirculation
filter can catch smaller particles, mist and outgas molecules,
generated from motor bearings, adhesives.  As the result, we can
eliminate contaminants which can exist at an interface of head-disk
and decrease flying height to get larger areal density.
