ABSTRACT:
The current invention substantially removes particulate waste materials or debris from the floptical medium after laser etching. A low-temperature gas containing ice crystals is applied at a predetermined angle while the floptical medium is being rotated to improve the cleaning effect. The temperature of the disk is maintained above freezing to maintain the cleaning effect.
