Mass Storage Device

Rapid access to a plurality of information-bearing media is highly desirable for high-performance data-processing systems.

A plurality of aligned media containing spools are each operatively associated with a pair of fixed media threading paths, extending respectively to a pair of media processing stations. The media on each of the respective media containing spools can be automatically threaded to either of the media processing stations. In the upper station MPU, a movable threading path is selectively positioned to one of the fixed media threading paths, for selectively receiving media from an addressed media containing spool. A flexible wall at 10 joins the movable threading path to MPU. In the lower part of the mass storage device, a plurality of fixed media threading paths is joined to form a common threading path at 12, for selectively conveying media from any of the spools to the lower media processing station MPL. Pneumatic transporting means plus a motor driving the various spools, effects media payout and takeup.

The number of spools available for simultaneous access is improved by providing various geometric arrays of such aligned spools in two-dimensional spool arrays. A Y-shaped array is suitably associated with three media processing stations MP, joined by a plurality of media threading paths. Each of the spools in the array can supply media to two different MB's, while center spool 13 can supply media to any MP. A cross-shaped s...
