Abstract

A disc cartridge having a case to accommodate a disc, a shutter to open or close an opening formed in the case to enable a recording and/or reproducing job with respect to the disc, a discharge path provided at one side of the case to allow the flow of air formed therein during rotation of the disc, and an opening/closing mechanism to open/close the discharge path. Thus, since the discharge path through which the flow of air produced inside the cartridge during rotation of a disc is smoothly discharged to the outside is provided, contamination of the disc by foreign material such as dust can be considerably reduced.
