Abstract
Device for the attenuation of the movement of the reel motors in recording devices during standstill of the tape capstan drive roller. The regulation of the reel motors proceeds during the normal run of the tape via the motor current and during the standstill of the capstan drive via the voltage which lies at the reel motors.
