とを特徴とするデイスクカートリツジ。[Scope of Claim for Utility Model Registration] A cartridge comprising a pair of upper and lower halves butted together and having a disk storage section formed inside, and a disk having a center hub stored in the disk storage section of this cartridge. The upper and lower halves are provided with a drive shaft insertion hole into which the center hub is loosely fitted, and at least the signal recording surface of the disk stored in the disk storage portion faces outward in the radial direction. In a disk cartridge provided with an opening, the disk storage portion provided in the upper and lower halves is arranged such that the inner wall of the disk storage portion and the side edge of the disk are connected in a direction perpendicular to a line connecting the drive shaft insertion hole and the opening. The gap should be larger than the gap between the side edge of the drive shaft insertion hole and the center hub, and the gap between the inner wall of the disk housing and the side edge of the disk should be larger in the direction parallel to the line connecting the drive shaft insertion hole and the opening. A disk cartridge characterized in that the gap is smaller than the gap between the side edge of the drive shaft insertion hole and the center hub.
