Information recording medium and information reproducing apparatus

摘要

An information reproducing apparatus for forming near-field light (31) at an information recording medium (30) and reproducing information by a reproducing probe (25) provided for scattering the near-field light, characterised in that fluxes of reflected and scattered light produced by scattering the near-field light produced at a unit of the information formed on the information recording medium by a front end portion of the reproducing probe, are detected at at least two position is symmetrical with each other in a left and right direction relative to the front end portion of the reproducing probe along a reading direction and a position of the reproducing probe is controlled in accordance with a detected signal, wherein the reproducing probe is formed in a wedge-like shape having symmetrical faces for reflecting and scattering the near-field light produced at the unit of information.
