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.
