Abstract

An information recording/reproducing apparatus capable of correctly reproducing information from a large number of recording tracks without requiring tracking servo. A recording medium is formed with at least one pilot track on which a pilot signal is recorded and a plurality of information data tracks which have the same track width as the pilot track and on which information data is recorded, where the pilot track and the information data tracks are arranged adjacent to each other. The information recording/reproducing apparatus comprises a plurality of reading units arranged in a width direction of the tracks, and each having a tracing width equal to or smaller than one half of a width of the track, a pilot signal detector for detecting the pilot signal from each of read signals read by each of the reading units, a track determining unit for determining a corresponding relationship between each of the reading units and each of the information data tracks in accordance with a detection result provided by the pilot signal detector, and a unit for sequentially selecting a read signal in accordance with a determination result provided by the track determining unit from the read signals to output the selected read signal as a read signal corresponding to each of the information data tracks.
