Part of the IBM 7-track family of tape units, it was used on late 700, most 7000 and many 1400 series computers. Like its predecessor, the IBM 727 and many successors, the 729 used 1 ⁄ 2 inch (13 mm) magnetic tape up to 2,400 feet (730 m) long wound on reels up to 10 + 1 ⁄ 2 inches (270 mm) diameter.
