Abstract
Tension is controlled in a recording medium fed from a roll by detecting a rotational velocity of the roll as the recording medium is fed, and applying a torque to the roll to maintain tension in the recording medium. The torque applied by the motor is controlled based on the rotational velocity of the roll.
