    摘要: 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.

    摘要翻译: 本发明提供一种收集在光学介质的激光蚀刻期间产生的废料的装置和方法,而不阻挡对介质表面的进入。 本发明还通过在介质的外边缘周围施加均匀的低压空气来提高收集效率。 由于在边缘周围施加空气压力,因此不需要协调本发明相对于激光蚀刻单元的移动或定时。
