PROBLEM TO BE SOLVED: To provide a disk cartridge device that does not require storage space for two pieces of disk medium, even if the two are stored in a casing and that will not cause problems in positioning, when they are set in a disk drive or in recording/reproducing information. SOLUTION: An annular drive ring 7, which turns linked with the sliding of a slider 6 for opening/closing a shutter 5, is arranged at the center of a casing 2, with a flexible tongue 8 provided at a proper position projectingly inward of the drive ring 7, storing two disk mediums 3, 4 with the drive tongue 8 held in-between. A tongue drive part 91, 92 is provided in the rotating area of the drive tongue 8, and at its rotation, the drive tongue 8 is guided by the drive part 91, 92 and bent in a suitable direction, causing one of the disk media 3 (4) placed on the driving tongue 8 to rise near the top face and securing the space for storing the other disk media 4 (3).
