ABSTRACT:
Four embodiments of disk cartridges are described. Each embodiment is made from a unitary blank of foldable material, such as paperboard or plastic. The cartridges are particularly useful for containing and protecting 130 mm optical disks. Shown are interior brackets integrally formed on panels of the cartridges and that extend to and engage a facing panel for both stiffening the cartridge axially of the contained disk and for physically restraining the contained disk from radial movements in the cartridge. The cartridge may have information containing holes. The interior brackets also stabilize the panel immediately adjacent the hole for enabling mechanical hole sensing. An interior bracket is shown as being integral with one end wall of the cartridge. Notches in two side walls of the cartridge are provided for facilitating automatic cartridge handling.
