<p>The current invention provides an apparatus and method of collecting waste materials produced during laser etching of a floptical medium (1) 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 (1). 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 (2).</p> |
