ABSTRACT:
A probe memory device carries out positioning with the use of a servo pattern provided in a servo area on a recording medium, and the recording medium and a probe head section are reciprocatingly moved (scan-moved) by vibration at a specific frequency in a one-axis direction. At this time, based on information from the servo area, relative position information between the recording medium and the probe head section is acquired, the relative position information is processed at a control section, and then, feedback control is carried out for carrying out position correction relative to an actuator.
