<p>PROBLEM TO BE SOLVED: To provide a magnetic recording device capable of preventing a malfunction by making difficult the flowing of a current between the + and -terminals of a control head during writing a program searching mark on a magnetic tape. SOLUTION: This magnetic recording device is provided with circuits 2 to 24 for detecting a control signal from the control track of a magnetic tape via a control head 1, and writing a program searching mark in synchronism with the detected control signal. Further, in the circuits 2 to 24, both terminals of the control head 1 are set to high impedance immediately before a detection period for detecting the control signal.</p> |
