ABSTRACT:
A disk cartridge includes a lower case having an opening formed thereon, an upper case installed at the lower case to be capable of being open and shut while pivoting, to accommodate a disk therebetween, a shutter installed at the lower case to be capable of sliding and opening and shutting the opening hole, a close covering member having an inclined surface installed at the shutter to be capable of sliding, closely contacting a non-information area disposed at an inner circumference of the disk when the shutter is closed, and being separated from the non-information area disposed at the inner circumference of the disk when the shutter is open. Thus, when the shutter is closed, introduction of dust is prevented so that the possibility of the information area of the disk being contaminated is lowered. Also, since the disk is fixed between the upper and lower cases, while the disk is carried, noise and damage can be reduced.
