Abstract

A disk carrier consists of a sealed drum with a central screw on which magnetic recording disks are stacked and an inflatable liner around the periphery of the disks to hold them in place during shipment. A cover and seal on the drum preserve the disks in a state of cleanliness suitable for direct use in s disk file assembly line. The disks can be raised and lowered by rotation of the screw.

Inflatable Sealed Disk Carrier

A disk carrier consists of a sealed drum with a central screw on which magnetic recording disks are stacked and an inflatable liner around the periphery of the disks to hold them in place during shipment. A cover and seal on the drum preserve the disks in a state of cleanliness suitable for direct use in s disk file assembly line. The disks can be raised and lowered by rotation of the screw.

As shown in the drawing, the carrier consists of an outer drum 10 made of a rigid plastic material and movable on wheels 11. Clean disks 12 are stacked on a central worm screw 13 and are spaced from each other by spacers 14.

A plastic liner 15 around the inside wall of the drum is inflated to support the disks 12 by their edges and restrain them against movement during shipment. Inflation of the liner is effected through valves 16 by way of a ballast chamber defined by plate 17. The ballast chamber maintains pressure in the liner when the air supply is not connected. A cover 18 and O-ring seal 19 close the container to prevent contamination of the disks.

After shipment, the exterior of the carrier is spray cleaned and can then be opened in a clean room area of the assembly line to permit removal of the disks. These disks can be used directly for file assembly without further treatment.

Loading and unloading of the disks are effected by means of motor 20 which rotates the worm screw 13 against the restoring force of a spring (not shown). The spri...
