Abstract: An optical information reproducing device and method of controlling the device capable of correcting a tracking remaining error component of a tracking error signal. The device includes a detector for detecting light of a laser beam reflected from a surface of an optical disk by a plurality of optical detectors and outputting a plurality of electric signals based on the detected reflected light, first delay circuits connected to the detector and capable of retarding one portion of the plurality of electric signals by a delay in a first predetermined range, and second delay circuits connected to the detector and capable of retarding another portion of the plurality of electric signals by a delay within a second predetermined range.
