Abstract

This arrangement is for driving tape from supply reel 1 to takeup reel 2. Reels 1 and 2 are placed in contact with hard surface rolls 3 and 4. Magnetic head 5 is placed between rolls 3 and 4. Drive wheel 6 has a soft outer periphery and is placed in contact with rolls 3 and 4. When tape is driven from reel 1 to reel 2, there is more pressure placed between wheel 6 and roll 4 than there is between wheel 6 and roll 3. This results in roll 4 tending to rotate faster than roll 3 and, correspondingly, reel 2 tends to be driven faster than reel 1. This results in a control of the tape tension. When the tape is to be driven from reel 2 to reel 1, there is more pressure placed between wheel 6 and roll 3 than between wheel 6 and roll 4. This results in the tendency of roll 3 and reel 3 to be driven faster than roll 4 and reel 2.
