    摘要： Information is recorded/reproduced by focusing a light beam in/from an optical recording medium capable of forming therein marks for information recording in a plurality of three-dimensional directions including an arbitrary directions and at least depth direction. Specifically, the optical beam is sequentially focused at a recorded mark position adjacent an optically recorded mark position, at which a recording/reproducing operation is started, in any directions regardless of the directionality of the plurality of three-dimensional directions, to cause the focused position of the light beam to describe a predetermined locus having a predetermined rule to rapidly and continuously record/reproduce the information. Thus, it is possible to efficiently and rapidly record and reproduce information in an optical recording medium capable of recording high-density information in three-dimensional directions, and it is possible to rapidly and efficiently record and reproduce information using such an optical recording medium.
