Abstract

The amplitude of the read signals from a magnetic head can be used to control the tape tension applied to the tape in a reel to reel tape drive. The amplitude of the read signal is monitored and directed to a drive microprocessor to adjust the tension in the tape as a result of the amplitude. If the signal is too low, the tape tension is increased. If the amplitude is too high, the tape tension is decreased. The adjustment to the tape tension causes the tape to change flying height and thereby change the amplitude of the sensed signals from the tape.
