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 (411) for supplying a drive signal to the scanning mechanism so as to permit the probe to scan the recording medium circumferentially, an oscillation circuit (409) for performing micro-vibration of the probe in a direction perpendicular to the data string, a detection circuit (410) for detecting a signal that corresponds to a positional deviation of the probe from the data string, and a multiplier (505,506,710,711) for multiplying the signal that is detected and the drive signal. |
