Claims

[Scope of utility model registration request]

In a disk cartridge comprising an upper case and a lower case and rotatably storing a disk-shaped recording medium in a space formed by joining the two cases, the inner surfaces of the upper case and the lower case 2 supporting non-recording areas formed on the inner and outer circumferences of the disc-shaped recording medium;
A first annular support member protruding from the inner periphery of the upper case and the lower case is set such that the height of the first annular support member protruding from the inner periphery of the upper case and the lower case is set such that the first annular support member protrudes from the inner periphery of the upper case and the lower case. A disk cartridge characterized in that the height of the second annular support member is higher than that of the second annular support member.
