Zusammenfassung:There is provided a new and useful protective cover for an optical disc of circular configuration having a circular aperture centred therein and having an outer edge. The protective cover comprises a sheet of film of generally circular configuration corresponding to the configuration of the disc, the film of a material that will not interfere with the read process of the disc when the cover is in place about the disc, and a plurality of clasps spaced about a circumferential edge of the film to engage the disc about its outer edge in a snap fit. The invention also relates to a method of applying such a protective cover to such an optical disc comprising the steps of holding the cover with the clasps in a closed position oriented relative to the film toward said disc, expanding the clasps to an open position wider than an outside diameter of the disc, placing the disc within the expanded clasps, concentric with the cover and returning the clasps to the closed position whereby they engage the disc about the outer edge in a snap fit.
