The present invention relates to a cartridge and a method that can sweep away dust or the like from a recordation medium housed in the cartridge in a simple way without adversely influencing recording and replaying of the recordation medium. The cartridge includes a shutter opposed to a surface of the recordation medium, a cleaner member, a support for supporting the cleaner member, and a sweeping mechanism actuated upon opening and closing movements of the shutter. The support pivots in a plane substantially in parallel to the surface of the recordation medium when the sweeping mechanism is actuated. When the sweeping mechanism moves forwards, the cleaner member moves without contacting the recordation medium surface. When the sweeping mechanism moves backwards, the cleaner member moves in contact with the recordation medium surface to clean the recordation medium surface.
