Abstract: A continuously moving information-bearing article carrier and a selectively actuated article handler are in peripheral velocity synchronism for exchanging information-bearing articles. Such dynamic article exchange occurs without stopping or altering the velocity of the carrier. In a preferred form, the carrier is a rotating cylinder having a large plurality of information-bearing articles spaced about its periphery and extending outwardly of the outer periphery for facilitating dynamic article exchanges. Tiers of such rotating cylinders may be axially aligned with a plurality of article handlers for each of the rotating cylinders; or one or more of the article handlers can move axially of the assembly for selectively accessing any one of the cylinders. In a data staging environment, a small plurality of such cylinders may have a plurality of spaced-apart accessing mechanisms for reducing total access time to any article in such rotating cylinder. Additionally, other cylinders may be selectively accessed by a traveling access mechanism which selectively transfers an article from one of the other rotating cylinders to the staging rotating cylinder. Several embodiments of the invention are described.

Abstract: A flexible disk file signal storage apparatus has a multiplicity of relatively thin, flexible disks of varying radii and arranged axially to facilitate radial disk selection. The radii pattern tends to minimize radii differences, thereby enhancing storage capacity. The flexible disks are arranged in axial groups of more than three disks with at least one disk in each group having a minimum radius with a pair of outer disks with a maximum radius plus at least one intermediate diameter disk. By interleaving alternate ones of said minimum radius disks between intermediate and maximum radius disks, radial selection access ports are maximized along an axial direction for a given radial difference between the maximum and minimum disk radii.
