摘要: A hologram recording and reproducing apparatus includes a movable galvanomirror, mirror controller reproduction unit. The galvanomirror guides reference beam toward medium changes the incident angle of beam. causes to move for adjusting predetermined recording. In recorded information, move, so that continuously within range including angle. unit receives detection signal from an optical detector while continuously. corresponds intensity reflected medium. reproduces based on signal, when is over level or reaches maximum.
