Abstract: The magazine particularly for magnetic diskettes, includes nearly square side panels, and oblong top and back panels and a bottom connecting the side panels leaving one end of the magazine open for withdrawal of diskettes stored therein. The inside surfaces of the top panel and bottom have corresponding grooves formed in them for reception of the diskettes in vertical disposition. The grooves in the bottom are narrower than the grooves in the top to provide accurate positioning of the diskettes at their bottoms while allowing a little warp of the diskettes about vertical axes. The inside surface of the back panel is plane and unribbed to accommodate sight diskette warp about horizontal axes.

Abstract: MAGAZINE-LID COMBINATION FOR JACKETED MAGNETIC DISKS A magazine particularly for jacketed magnetic disks (which may be termed "diskettes") of the type disclosed in U. S. Patent 3,668,658 of Flores et al., issued June 6, 1972, and a lid fitting on a forward, sometimes open, end of the magazine. The lid has internal ribs for supporting weak side edges of the diskettes in the magazine particularly when the magazine is turned on its side, and the magazine has aligned internal bottom and top diskette supporting ribs. A swing connection is provided between the lid and the magazine adjacent the top of the magazine including L-shaped slots formed in side panels of the magazine extending from the forward edges thereof horizontally and then upwardly and a pair of pins carried by the lid and fitting in the L-shaped slots. The lid when placed on the magazine thus first moves horizontally but slanting forwardly and downwardly to first move the upper ends of its internal ribs between the diskettes and then upwardly and in swinging movement to close the magazine. The upper edge of the lid is chamfered to allow such swinging placement of the lid on the magazine. A U-shaped spring retainer releasably holds the lid closed.

Abstract: DISK FILE ACCESS MECHANISM An access mechanism for a vertical stack of magnetic disks including a mechanism carriage moveable back and forth horizontally by a prime mover, an access arm having a magnetic head adjacent its end and carried by a carriage moveable along slide shafts mounted in the mechanism carriage at an angle with respect to horizontal and a stop against which the access arm carriage moves whereby the access arm moves vertically along the periphery of the disk stack as the movement of the mechanism carriage progresses after contact of the access arm carriage with the stop. A pawl carried by the mechanism carriage coacts with ratchet teeth carried by the access arm carriage for holding the access arm and magnetic head at selected vertical positions so that the access arm and head may be moved between a selected pair of disks in the stack by movement of the mechanism carriage in the opposite direction.

Abstract: A magazine particularly for magnetic diskettes, such as of the type disclosed in U. S. Patent 3,668,658, including nearly square side panels, and oblong top and back panels and a bottom connecting the side panels leaving one end of the magazine open for withdrawal of diskettes stored therein. The inside surfaces of the top panel and bottom have corresponding grooves formed therein for reception of the diskettes in vertical disposition, and the grooves in the bottom are narrower than the grooves in the top to provide accurate positioning of the diskettes at their bottoms while allowing a little warp of the diskettes about vertical axes. The inside surface of the back panel is plane and unribbed to accommodate slight diskette warp about horizontal axes. A spring wire retainer extends upwardly from the magazine bottom across the lower part of the open end of the magazine to releasably retain diskettes in the magazine, and the side panels are notched close to the magazine bottom to allow an easy gripping of the diskettes adjacent the magazine bottom for withdrawal of the diskettes.
