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. 1. An apparatus comprising: a means for detecting recorded information, and a position of the disc irradiated by the recorded information detection beam and the emitted light beam is set to be on a circular arc connecting the same radius of the disc.
