A tape drive capstan and back-up roller are located adjacent the tape cassette compartment. A motor is located at the opposite end of the dictating machine from the tape cassette compartment, and a multi-stage speed reduction belt and pulley drive system is located between the motor and the drive capstan for simultaneously driving the drive capstan and the tape reel driving spindles at a uniform rate of speed.
