Early IBM tape drives, such as the IBM 727 and IBM 729, had been mechanically advanced ground-standing drives that employed vacuum columns to buffer very long u-shaped loops of tape. Concerning servo control of potent reel motors, a reduced-mass capstan push, along with the reduced-friction and controlled rigidity from the vacuum columns, fast start and quit of the tape on the tape-to-head interface could possibly be achieved.[a] The quick acceleration can be done as the tape mass while in the vacuum columns is modest; the duration of tape buffered inside the columns gives time for you to speed up the significant-inertia reels.
