ABSTRACT:
In an information processing apparatus for recording and/or reproducing a circumferential data string from a recording medium, there are provided a scanning mechanism for performing relative movement of the probe and the recording medium so that the probe scans the recording medium, a driving circuit for supplying a drive signal to the scanning mechanism so as to permit the probe to scan the recording medium circumferentially, an oscillation circuit for performing micro-vibration of the probe in a direction perpendicular to the data string, a detection circuit for detecting a signal that corresponds to a positional deviation of the probe from the data string, and a multiplier for multiplying the signal that is detected and the drive signal.
