  • Exhaust and particle wastes collecting device for laser etching
    Patent number: 5362941
    Abstract: The current invention provides an apparatus and method of collecting waste materials produced during laser etching of a floptical medium without blocking access to the medium surface. The invention also improves collection efficiency by applying a uniform low-pressure air around the outer edge of the medium. Because the air pressure is applied around the edge, there is no necessity to coordinate a movement or timing of the current invention with respect to the laser etching unit.
