Abstract
A disc cartridge according to the present invention includes a cartridge body, a shutter and a disc holding portion. The cartridge body includes a disc storage portion, a chucking opening and a head opening. The disc storage portion stores a disc, having first and second sides, therein so that the disc is rotatable in the disc storage portion. The shutter is supported to, and movable with respect to, the cartridge body between the disc and the bottom of the disc storage portion so as to expose or cover the chucking opening and the head opening. The disc holding portion is provided at a portion of the shutter for fixing the disc onto the shutter or the cartridge body synchronously with a movement of the shutter, by pressing the disc toward the bottom of the disc storage portion when the shutter covers the chucking opening and the head opening.
