Abstract

A method for removing particulate contamination from the surface of optical storage disks is described which involves the use of forced or compressed air in a specially constructed device. This method allows optical media to be cleaned without removing it from its cartridge. The device provides a frame for inserting an optical disk, a mechanism to open the cartridge cover, and a magnetic spindle to attach the disk to a hub so that it can freely rotate in its cartridge. Forced or compressed air is introduced externally through a channel air guide that directs flow at an angle across the disk diameter. This action causes both disk rotation and cleaning action to remove particulate contaminants from the disk surface. The air and contaminants exit the device at an appropriate position near the disk outer diameter.

Optical Disk Cleaner Using Forced or Compress Air

      A method for removing particulate contamination from the
surface of optical storage disks is described which involves the use
of forced or compressed air in a specially constructed device.  This
method allows optical media to be cleaned without removing it from
its cartridge.  The device provides a frame for inserting an optical
disk, a mechanism to open the cartridge cover, and a magnetic spindle
to attach the disk to a hub so that it can freely rotate in its
cartridge.  Forced or compressed air is introduced externally through
a channel air guide that directs flow at an angle across the disk
diameter.  This action causes both disk rotation and cleaning action
to remove particulate contaminants from the disk surface.  The air
and contaminants exit the device at an appropriate position near the
disk outer diameter.  Forced or compressed air cleaning minimizes the
possibility of scratching the disk surface which is a concern of
methods involving rubbing the disk surface with a cloth or brush as a
means of cleaning.
