The figure is a block diagram of a reel servo system of a magnetic tape device. Sequence control during loading/unloading and feedback control after column input are switched by a selector circuit. When loading/unloading, it is necessary to realize the motor rotation speed set by the 1 micro program, but here, as shown in the m2 diagram, the numerical value and rotation direction according to the rotation speed are set in the EO boat by the micro program. Then, the DA converter outputs a DC voltage whose polarity is uniquely determined by the direction of rotation and whose acid ratio is proportional to the set numerical value. This output is converted into a pulse width by the PVII Henken circuit. Since there is no control in feedback control, the motor can be driven by a common drive circuit by switching the selector circuit. Furthermore, since a pulse width proportional to the value set in the 1 micro program is obtained, the rotation speed of the driven motor is also proportional to the set value.

In addition, fine rotational speed control is possible without switching the motor characteristics (field switching) or feedback on the rotational speed, so it is effective to downsize the motor and reduce costs by permanently using 8 stones and eliminating the tachometer.
