A compact tape cassette or cartridge storage and accessing system (22) includes a longitudinally extending frame with two endless link chains (48, 50), one on each side of the frame; and cassette carriers (32, 34) are mounted in two layers by linkages (52, 54) to the chains, with one layer moving forward and the other to the rear. At the ends, a cam follower (62) on each cassette carrier, and a control groove (78), and associated guide and latch members (72), 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<3/4> inches, for compatibility with standard electrical equipment racks.
