Abstract
A disc cartridge having a disc to record information and a case to accommodate the disc includes a cleaning unit installed inside the case and selectively contacting or being separated from the disc depending on a flow of air generated during a rotation of the disc, so that the cleaning unit removes foreign material adhering to a surface of the disc when contacting the disc. Since cleaning is automatically performed depending on the flow of air, inconvenient manual operation is not necessary. Furthermore, since the cleaning unit does not deviate from a disc area, miniaturization of the disc cartridge or disc recording and reproducing apparatus is possible.
