Zusammenfassung:	PROBLEM TO BE SOLVED: To attain the increase of density by using a three-dimensional recording/reproducing method. SOLUTION: In the three-dimensional recording/reproducing device provided with a recording medium 4 laminating a plurality of recording layers 1 on the substrate 3 and an optical system for three-dimensionally recording or reproducing the information by converging the light from the side of a substrate 3 to each of a plurality of recording layers 1, an inter-layer moving means is driven by a pair of pulses with different polarities.
