Abstract
A disc cartridge is comprised of a cartridge body accommodating a disc-shaped record medium being formed of a pair of cartridge halves, each of which has an opening extending from a central portion of at least one of the pair of cartridge halves to a peripheral wall thereof to expose one portion of the disc-shaped record medium rotatably accommodated therein to the exterior of the cartridge body, a portion of the peripheral wall to which the opening extends being thinner than the remainder of such peripheral wall. A reinforcing member of a material having a mechanical strength higher than that of the pair of cartridge halves reinforces the thinner portion of the peripheral wall to which the opening extends.
