Abstract
A motor servo circuit is disclosed. The motor in the motor servo circuit is driven by an output which is obtained by logically adding output pulses of a pulse stretcher circuit which stretches a pulse width of error pulses generated from an OR circuit when pulses inputted to the motor servo circuit and pulses outputted from a pulse generator in response to the input pulses are different in the pulse width to pulses having a predetermined pulse width which are generated at intervals of a predetermined member of the error pulses synchronizing therewith.
