PROBLEM TO BE SOLVED: To make a recording disk cartridge compact by simplifying structure of a shutter of a recording disk cartridge storing a plurality of flexible recording disk media. SOLUTION: A plurality of magnetic disk media 41 being an example of magnetic disk media are housed in a cartridge case 2. The cartridge case 2 comprises a lower plate 10 constituting a lower wall being parallel to the magnetic disk media 41, an inner plate 20 laminated and fixed on the lower plate 10 and partitioning the plurality of magnetic disk media 41, an upper plate 30 laminated and fixed on the inner plate 20 and constituting an upper wall of the cartridge case 2. And a shutter 4 comprises a lower rotor 51 supported rotatably at an inner plane side of the lower plate 10, an upper rotor 52 supported rotatably at an inner plane side of the upper plate 30, and a shutter plate 51b provided so as to couple the lower rotor 51 and the upper rotor 52.
