A MAGNETIC RECORDING DISK CARTRIDGE ABSTRACT OF THE DISCLOSURE A magnetic recording disk cartridge includes a casing having upper and lower halves mated together to define a planar spacing in which a magnetic recording disk supported by a hub member is rotatably held, and fluctuation suppressing ring members are disposed within the casing to be axially spaced from one another via at least an outer peripheral portion of the magnetic recording disk. The fluctuation suppressing ring members aerodynamically maintain the magnetic recording disk at an intermediate position in the planar spacing of the casing during the rotation of the magnetic recording disk.
