An information recording/reproducing apparatus having two light sources, one of which is for use in recording information and the other one of which is for use in reproducing information, in which during action when information is recorded on an information recording medium in the apparatus, tracking errors of light beams emitted from the two light sources are corrected with the aid of a tracking error signal detected from reflection light beams of light beams emitted from a light source for use in recording information. Therefore, the light beams spot of the light beam for use in recording information can be positioned at a center portion of a data track without regard to a relative positional relation between the light beam for recording information and the light beam for reproducing information.
