EXHAUST AND PARTICLE WASTES COLLECTING DEVICE FOR LASER ETCHING. |
摘要 |
<p>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.</p> |
