Abstract

Plastic cartridges C contain magnetic memory discs D mounted on central steel hubs H. Each hub H rests on the lower wall of the opening in cartridge C provided for hub H. Cartridges C are carried in a container having side walls S, with grooves G for holding cartridges C. Springs F hold cartridges C accurately in grooves G, and provides electrical contact with the cartridges in the system.

Multidisk Cartridge Access Device

Plastic cartridges C contain magnetic memory discs D mounted on central steel hubs H. Each hub H rests on the lower wall of the opening in cartridge C provided for hub H. Cartridges C are carried in a container having side walls S, with grooves G for holding cartridges C. Springs F hold cartridges C accurately in grooves G, and provides electrical contact with the cartridges in the system.

Read/write head HE is locatable by sliding on square shaft 19 between cartridges C to read discs D. Two sets of piston adders, not shown, operate on HE along the x axis with shaft 30 and normal to the page through 31 to turn shaft 19 to locate head HE at the correct disc and track, in response to binary signals. Cylinder 12 houses a reciprocable mandrel M composed of a continuous glass filament helical coil wrapped tightly and impregnated with a plastic, such as nylon sealant, to provide walls 18 of a fluid tight resilient chamber 13. Mandrel M rides reciprocably on guide bearing B within cylinder 12 and is spring biased to the left by compression spring Y, which is wrapped on shaft 14 and bears on head 15 at one end of shaft 14. End wall W of cylinder 12 receives pressure from spring Y tending to drive it left towards end E of cylinder 12, because shaft 14 is affixed to end E.

Hydraulic or pneumatic fluid under pressure PR is admitted via orifice O to space 23 in cylinder 12, and through aperture A in wall W to the interior of mandrel M to dri...
