A control signal generating circuit for a magnetic recording and/or reproducing apparatus comprises a monostable multivibrator for producing a pulse signal having a predetermined pulse width in response to a reference signal from a supplying circuit of the recording and/or reproducing apparatus, a flip-flop circuit responsive to the output pulse signal of the monostable multivibrator, for inverting an output thereof every time the pulse signal is supplied thereto, and an OR gate for producing a control signal responsive to the output pulse signal of the monostable multivibrator and the output of the flip-flop circuit, and for supplying the control signal to a control head, of the recording and/or reproducing apparatus, which records and/or reproduces the control signal on and/or from a magnetic tape.
