Abstract
A tension feedback signal is generated to reduce tension variation on a tape occurring at a reel frequency. Tension variation information may be obtained and used to generate the tension feedback signal. The tension feedback signal may be combined with a constant tension preset signal. The combined signal may be used to drive a tape reel at a tape reel speed adjusted according to the combined signal.
