ABSTRACT:
A recording disk cartridge comprises a housing in which at least one recording disk may be mounted for rotation about its axis. The housing has a peripheral side wall about which a ridge is formed, the ridge being defined by a plurality of sections at least some of which are spaced from one another in a direction parallel to the axis of rotation of a disk mounted in the housing. The dimensions and spacings of the ridge sections are such that the contour of the peripheral side wall at the lower surface of the ridge is the substantial complement of the contour of the peripheral side wall at the upper surface of the ridge. The cartridge also comprises a cover including a peripheral side wall having a contour at its upper surface substantially the same as that of the peripheral side wall of the housing at the lower and upper surfaces of the ridge. The cover may thus be disposed over the lower end of the housing with the upper surface of the peripheral side wall of said cover seated against the lower surface of the ridge, and may also be disposed upside-down over the upper end of the housing with the upper surface of the peripheral side wall of the cover seated against the upper surface of the ridge.
