A disk cartridge provided with a cartridge body formed by mating and connecting an upper half and a lower half and accommodating a disk on which are recorded data signals. Disk supports are provided, corresponding to the non-signal recording region of the inner periphery of the disk accommodated in the cartridge body, at the inside surfaces of the cartridge body. At the surfaces of the disk supports facing the disk, disk support members having a high wear resistance and a high lubricity are provided and are spread in a ring-like manner at predetermined intervals from each other. The Disk support members are formed from sheet-like members of ultra-high molecular weight polyethylene or sheet-like members comprised of polyfluoroethylene fibers. By providing the disk support members spread out in this way, it becomes possible to reliably and easily attach them to the disk supports.
