Abstract
In an information recording/reproducing apparatus for effecting recording/reproduction of information using a probe, a recording bias is applied to between a recording medium and the probe to record information on the recording medium. A current flowing through the recording medium and the probe is detected. The detected current is determined whether it exceeds a predetermined value. When the detected current exceeds the predetermined value, the application of the recording bias is stopped after a predetermined time.
Claims4
