A reel-to-reel tape drive system is disclosed in which primary control signals are applied to motors to drive both the payout and takeup reels and in which secondary control signals are provided to first and second torque driving circuits which, responsive to the secondary control signals, continuously provide first and second tensioning control signals to the first and second reel motors respectively. The first and second tensioning control signals operate to activate the first and second reel motors to take up slack and provide tension in the tape when the first and second reel motors are not receiving primary control signals. Thus, slack is taken up when the reels are stopped and adequate tension is supplied prior to restart, enhancing starting and stopping performance of the tape transport mechanism.
