Abstract
The walls of a video disc caddy are vibrated at or near their resonant frequency to dislodge foreign matter adhering to the inside surfaces of the walls. The separated foreign matter is collected by the pressurized air circulating inside the caddy enclosure, and removed therefrom by means of a vacuum.
