摘要

An information reproducing apparatus for reproducing information from a track of an information recording medium (80) having the information recorded on it, the information reproducing apparatus comprising: a probe (83) having a microscopic aperture (84) for producing near-field light (5), wherein the microscopic aperture (84) is formed having an interval in a direction of the track, the interval increasing constantly or gradually in one direction perpendicular to both a direction along the track and a direction of a depth of the medium; photo-detecting means (6,7) for detecting reflection scattering light caused due to scattering of the near-field light (5) by the information and outputting a detection signal; and probe position control means (14) for controlling a position of the probe (83) according to an intensity of the detection signal.
