Abstract

Writable optical storage devices require external airflow to cool electronic components. This airflow can also lead to contamination of optical and mechanical components thereby degrading performance and reliability of the device. Described is a method that separates the optical storage device into two discrete compartments by use of a divider plate. The divider plate isolates electronic components into a separate airflow plane from the optomechanical subassembly. Airflow can enter the electronics plane through slots on the device's faceplate; but, is prevented from entering the contamination sensitive areas of the device because of the divider plate. Airflow to the optomechanics subassembly is reduced with the use of a shutter on the media cartridge slot.

Reduction of Optical Storage Device Contamination

      Writable optical storage devices require external airflow to
cool electronic components.  This airflow can also lead to
contamination of optical and mechanical components thereby degrading
performance and reliability of the device.  Described is a method
that separates the optical storage device into two discrete
compartments by use of a divider plate.  The divider plate isolates
electronic components into a separate airflow plane from the
optomechanical subassembly.  Airflow can enter the electronics plane
through slots on the device's faceplate; but, is prevented from
entering the contamination sensitive areas of the device because of
the divider plate.  Airflow to the optomechanics subassembly is
reduced with the use of a shutter on the media cartridge slot.  This
overall design leads to efficient cooling of the necessary components
while also significantly reducing the buildup of particulate
contaminants on sensitive optical components.
