Flexible disc cartridge

Abstract

A flexible or "floppy" disc such as is used for data storage is retained within an enclosure that substantially protects it from contaminants or damage from handling while not in use but still permits ready access to the disc by a machine. A hub nests the disc in a bore on a tray which is received by an envelope-type of housing so that a complete enclosure is provided. The flat surfaces of the housing act to retain the disc hub within the bore while in the cartridge. A latching arrangement between the tray and the housing permits either manual or machine release of the tray. The entire housing containing the tray and the disc is readily adapted to loading within a machine by means of a hub-engaging spindle to lift the disc from the tray after it has been removed from the housing. Strategically located ridges guide the disc hub into proper tray engagement when the disc is stored in the cartridge. A plurality of slots on the tray augment air flow under the disc. Various features of the tray and housing further improve proper disc and tray alignment as well as machine adaptability.
