Abstract

A disc or record cleaning device especially for laser-read discs having digital recordings is provided in a disc storage container and incorporates a cleaning member with which the disc or record is brought into contact so as to clean the disc by a relative movement with respect to the cleaning member. The cleaning member is a fibrous pad and is either fixed and the disc rotated or the disc is held stationary and the cleaning pad rotated or translated. The storage container is provided by sections movable relative to one another, either articulated about a common pivot or translatable. The relative movement of the sections is coupled to move the disc and cleaning member relatively for cleaning the disc.
