Abstract
An apparatus and method for cleaning components internal to an optical recording system without requiring the optical recording system to be disassembled. The apparatus is comprised of inlets through which pressurized gas is fed. The pressurized gas is directed through channels within the apparatus to various outlets. The pressurized gas is then expelled from these outlets. When the apparatus is inserted in the optical recording system, the outlets are located next to components sensitive to particle contamination. Thus, the expelled gas removes the particle contaminants from the surfaces of the components, thereby enhancing operation of the optical recording system.
