Title (EN) A METHOD OF AND APPARATUS FOR REMOVING DEBRIS FROM THE FLOPTICAL MEDIUM
(FR) PROCEDE ET APPAREIL SERVANT A ENLEVER DES DEBRIS D'UN DISQUE SOUPLE OPTIQUE
Abstract:
(EN) A method and apparatus for removal of particulate waste materials or debris (10) from the floptical medium (1) after laser etching. A low temperature gas containing ice crystals (4) is applied at a predetermined angle while the floptical medium (1) is being rotated to improve the cleaning effect. The temperature of the disk (1) is maintained above freezing to maintain the cleaning effect.
(FR) Procédé et appareil permettant d'enlever des débris ou des déchets particulaires (10) d'un disque souple optique (1) après que celui-ci ait été soumis à une gravure au laser. Un gaz à basse température, contenant des cristaux de glace (4), est appliqué à un angle prédéterminé tandis que ledit disque (1) est mis en rotation afin d'améliorer l'effet nettoyant. La température du disque (1) est maintenue au-dessus du point de congélation afin de prolonger l'effet nettoyant.
