An optical information reproducing device, takes advantage of holography and can precisely detect a well-known pattern disposed at a prescribed location within a page and is used for correcting position deviation, rotation deviation, and magnification deviation. The optical fiber reproducing device includes a detection unit that detects the position information of a marker as a well-known pattern from a page as a 2-dimensional reproduction signal from a hologram, a detection error position estimating unit that estimates presence/absence of detection error in the position information of the marker and estimates the position where the detection error occurs if there is detection error, a position correcting unit that corrects the marker position information of the detection error position specified by the detection error position estimating unit, and a signal detection unit that detects each signal from within the page based on the corrected marker position information.
