Abstract
A disk cartridge comprises a flexible disk rotatably mounted in an outer casing. The outer casing comprises upper and lower shells that mate to form the casing. Each of the upper and lower shells has an inner surface disposed in facing relation to a respective surface of the disk. A number of radially extending stabilizers are arranged on the inner surfaces of the upper and lower shells so as to induce a predetermined standing wave pattern in the flexible disk as the disk spins at high speeds, and to maintain the standing wave patter as the recording heads of a disk drive move radially over the surface of the disk. Additionally, at least one pair of opposing projections are disposed on the inner surfaces of the upper and lower shells near a head access opening in the front peripheral edge of the cartridge. The opposing projections have a spacing, S, and serve to center the edge of the disk during head loading operations.
