ABSTRACT:
A recording current setting method comprises the steps of: recording signals on a tape by changing, by steps, recording current for the tape; detecting a reproduced signal level at each recording current; and determining an optimal recording current from a middle point between a first recording current at which a reproduced signal level first exceeds a threshold level as a result of increasing, by steps, the recording current and a second recording current at which a reproduced signal level first exceeds the threshold level as a result of decreasing, by steps, the recording current. An information signal recording apparatus using the method is also disclosed.
