A high density tape library includes a plurality of rectangular platforms mounted adjacent one another for movement in a plane, with tape cassette magazines mounted on the platforms. The platforms have depending guide and cam follower members for movement around a generally rectangular track under the control of a series of cams. At a cassette handling station, selected tape cassettes are shifted from a magazine to a tape drive.

High density tape library system

A compact tape cassette or cartridge storage and accessing system includes a longitudinally extending frame with two endless link chains, one on each side of the frame; and cassette carriers are mounted in two layers by linkages to the chains, with one layer moving forward and the other to the rear. At the ends, a cam follower on each cassette carrier, and a control groove, and associate guide and latch members, tilt the cassette carriers to smoothly shift them from one layer to the other. With 8 mm tape cassettes, the height of the system is within 1&frac34; inches, for compatibility with standard electrical equipment racks.
