contamination control
REV PRO removable hard drive-based media have been
designed with a comprehensive set of tools that control
and mitigate the effects of contamination. The result
of extensive research and practical testing led to the
development of a simple contamination strategy for REV
PRO: start clean, stay clean.
REV PRO employs a unique, patented labyrinth-type
design, which features multiple seals for a very effec-
tive barrier to outside contaminants such as airborne
particulates, gasses, and corrosion. A unique two-stage
shutter mechanism does not open until the disk is com-
pletely seated in the drive. This start-clean, stay-clean
mechanism is designed to keep the heads and media in
a virtual clean room environment.
REV PRO incorporates a charcoal desiccant inside each
cartridge to provide additional protection from mois-
ture, corrosion, and out-gassing. Advanced filtration,
automatic head cleaning, and robust two-stage error
correction are employed to ensure high data integrity
and reliability. The media design also includes a robust
recirculation filter on each cartridge to filter the air inside
the cartridge each time the disk spins, effectively remov-
ing any airborne contaminants that made it past the
cartridge seal.
As a comparison, videotape and optical disks are open
media with few safeguards against exposure to outside
elements that can contaminate or optically block record-
ing heads and erode stored media.
