<p>PURPOSE:To accurately record a program searching code by inhibiting the output of a picture recording time changeover switch during the recording of the program searching code. CONSTITUTION:A gate circuit 5 is provided to be controlled by an instruction signal 42 from a code generating circuit 4 and to output a changeover signal 61 for the state of a picture recording time changeover switch or to be as an inhibiting means with a function of holding the changeover signal 61, irrespective of the state of the switch 7. By this method, when the picture recording time changeover switch 7 is changed during the recording of the program searching code, the changeover signal 61 is held as before by the gate circuit 5, and a servo circuit 6 continues its control of a fixed speed condition. For this, the program searching code can accurately be recorded to a magnetic tape 1.</p> |
