特徴とする装置。A servo that detects a deviation in the orthogonal relationship between a recording disk and an optical axis of a recorded information detection light beam, and controls a tilting means for tilting the optical axis in accordance with this deviation to maintain the orthogonal relationship. In the recorded information reproducing apparatus, the means for detecting the orthogonal relationship includes a light emitting means for emitting emitted light toward the disk, and a light receiving means for receiving reflected light of the emitted light by the disk. and a beam radius of the emitted light on the disk is set to be smaller than the smaller length in the radial direction of the lead-in and lead-out portions of the disk. .
