A disk cartridge includes a lower case having an opening hole, an upper case for accommodating a disk together with the lower case, a shutter for opening and shutting the opening hole, and a close covering member closely contacting a non-information area at an inner circumference of the disk when the shutter is closed and being separated from the non-information area at an inner circumference of the disk when the shutter is open. Thus, when the shutter is closed, intrusion of dust is prevented so that the possibility of the information area of the disk being contaminated is lowered. |
