Abstract
In a two-dimensional probe array, an interval between the leading ends of probes adjacent to each other in an X direction is made shorter than that between the leading ends of probes adjacent to each other in a Y direction. Thus, the leading ends of the probes are arranged to form a lattice wherein many rectangles are arranged. Furthermore, the lowest resonance frequency of an actuator which moves a recording medium in the X direction is set higher than the lowest resonance frequency of an actuator which moves the recording medium in the Y direction. At the time of recording or reading information, the recording medium is reciprocated in the X direction at a frequency substantially equal to the lowest resonance frequency of the actuator.
