Fig. 1 shows a disk cartridge in which a single magnetic disk 1, having a central support hub 2, is contained within an enclosure comprising cover 3 and door 4, pivotable about point x. When off line, as in Fig. 1, disk 1 is restrained from rotation by a sprung base section 5 of the enclosure which urges flange 6 of hub 2 downwardly through a ring seal. Hub 2 includes a central pillar 8 having a tapering bore, for receiving a disk drive spindle therein, and a capping plate 9 which seals against an annular flange 10 extending inwardly from a well portion 11 of cover 3.
