Abstract
In a method or apparatus for reading information from each of a plurality of information tracks arranged in a longitudinal direction on an information recording medium by relatively moving the information recording medium the orthogonally to the longitudinal direction of the tracks relative to a sensor array for reading information from the information tracks, wherein relative skew between the direction of arrangement of sensors of the sensor array and the longitudinal direction of the track is detected, and information is read from the information tracks while the recording medium and the sensor array are relatively moved in the longitudinal direction of the information tracks and, if desired, while the sensor array and the recording medium are relatively moved in such a manner as to compensate for deviation of an information reading area of an information track from a proper position caused by the skew in the course of the relative movement, based on the result of the detection.
