DISK CARTRIDGE

摘要

A disk cartridge enabling the avoidance of damage to a disk-like recording medium resulting from a force applied to a cartridge body while enabling the exposure of an area starting at one outer edge part to the other outer edge part of the disk-like recording medium which are opposed to each other on both sides of a center hole. The disk-like recording medium is stored in the cartridge body (2) having a lower shell and an upper shell (4) formed so as to be fitted to each other. A disk access opening part (3a) is formed in the lower shell to enable the exposure of the area starting at one outer edge part to the other outer edge part of the disk-like recording medium stored in the cartridge body (2) which are opposed to each other on both sides of the center hole. A reinforcement member (7) formed separately from the upper shell (4) so as to cross the opening part (3a) of the lower shell in the state of being fitted to the upper shell (4) is fixed to the inner surface of the upper shell (4).
