<p>A disc cartridge is comprised of a cartridge body (4) and a reinforcing member (10). The cartridge body (4) is formed of a pair of cartridge halves (2, 3), each of which is made of a synthetic resin and has an opening portion (7, 8) extended from a central portion of at least one of the pair of cartridge halves to one side wall portion so as to expose one portion of a disc-shaped record medium (5) rotatably accommodated therein outside and a portion (7a, 8a) in which outer end portions of the opening portion of the one side wall portion are coupled is formed thin. The reinforcing member (10) is made of a material having a mechanical strength higher than that of the pair of cartridge halves (2, 3) to reinforce the thin coupling portion (7a, 8a) formed at the one side wall portion.</p> |
