A disc cartridge is comprised of a cartridge body for rotatably accommodating therein a disc and which has an opening portion from which the disc is partially exposed to the outside, and a shutter slidably attached to the cartridge body for opening and/or closing the opening portion, wherein the shutter is provided with first and second guide members, the first guide member is engaged with a first guide groove formed on a major surface of the cartridge body and the second guide member is engaged with a second guide groove formed on a side wall of the cartridge body. Thus, the shutter can be prevented from being disengaged from the cartridge body inadvertently or unintentionally. Further, in its opening and/or closing operation, the shutter can smoothly open and/or close the opening portion without being shaked.
