A square hard-cartridge diskette, housing a two-sided floppy disk, is constructed and arranged to be symmetrical about a diagonal axis, such that the diskette is oriented for use of one disk side, or the other, by rotating the cartridge 180.degree. about this diagonal axis. The diskette carries locating notches and polarizing edges which operate, respectively, to properly locate the diskette within a using disk drive, and to prevent improper insertion of the diskette into the disk drive. The locating notches and polarizing edges are located symmetrically relative this diagonal axis. Head-access openings and disk cleaning members are located on this diagonal axis.
