徴とするモータサーボ制御装置。 In a motor servo control device that controls the rotational speed and rotational phase of a capstan motor and a cylinder motor to a predetermined speed and phase corresponding to each mode of a video tape recorder, when changing modes, either the capstan motor or the cylinder motor a rotation control means for changing the rotation speed of one of the rotation speeds to a rotation speed corresponding to the mode to which the mode is to be transferred; a detection means for detecting the rotation speed of the capstan motor and the cylinder motor at the time of the mode transition; The detected rotational speeds of both motors are compared, and the rotational speed of the other motor is in a predetermined relationship with the current rotational speed of the motor whose rotational speed is being changed by the control means. A motor servo control device comprising: rotation adjustment means for changing the rotation speed of the other motor.
