First Claim
1. Apparatus for retaining a flexible disc comprising:
- a tray having an elongated outer edge and a flat plate perpendicular to said outer edge with a bore extending at least partially thereinto from the upper surface of said flat plate,a hub centrally mounted on said disc adapted for nesting engagement in said bore, anda housing for slidably receiving said tray and having upper and lower internal surfaces spaced for retaining said hub in said bore whenever said tray is inserted in said housing, said outer edge of said tray providing a complete enclosure of said tray in cooperation with said housing whenever said tray is inserted in said housing.

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.

5. Apparatus for removably retaining a flexible disc comprising:
-
a tray having an elongated outer edge and a flat plate extending perpendicular to said outer edge, said plate having a central bore and raised ridge portions located relative to said bore for engaging the outer peripheral meter of the disc, means on said elongated outer edge of said tray on the side thereof opposite to said flat plate for permitting machine removal of said tray from said housing, a hub centrally mounted on the disc for nesting engagement with said bore, and a housing arranged for slidably receiving said tray thereinto and for cooperatively engaging with said elongated outer edge of said tray for providing a complete enclosure for said tray, said housing having upper and lower surfaces spaced for retaining said hub in said bore whenever said tray is inserted in said housing. - View Dependent Claims (6, 7, 9, 10, 11, 12)
