し信号記録回路。 A full-width erasing head having a switching element that is turned on and off by a control signal for recording a cue signal, and an impedance element, the impedance of which changes according to the on/off state of the switching element, the full-width erasing head, and an audio It consists of an oscillator circuit that biases the erasing head and the audio recording head with alternating current.
In a magnetic recording/reproducing machine that uses the full-width erase head to perform deep recording on a magnetic medium using an AC bias signal outputted from the oscillation circuit in response to a change in impedance as a cue signal, the impedance element may be a resistor. Features a cue signal recording circuit.
