摘要：
A recording/reproducing system records/reproduces information in a three-dimensional optical recording medium wherein information is recordable at three-dimensional optional positions and wherein position reference regions having optical characteristics different from those of recordable regions are previously provided at predetermined positions, and for reproducing information recorded in the three-dimensional optical recording medium. The recording system comprises a light source, a detector, a moving mechanism, and a light intensity adjuster. The reproducing system comprises a light source, a condenser, a detector, a moving mechanism, and a reproducing device.
