<P>PROBLEM TO BE SOLVED: To provide an optical recording medium for continuous irradiation of light for reproduction or (and) recording to a plurality of laminated information sections. <P>SOLUTION: A first recording element 31, having a first optical translucent information section 31M on one surface of a first light transmission substrate 31S, and a second recording element 32 having a second reflective information section 32M on one surface of a second substrate 32S are joined via a transparent layer 33, by allowing surfaces at sides having the first and second information sections to face each other. The recording tracks of the first and second information sections are arranged coaxially. The rotation recording travelling direction of each recording track is selected to a rotation recording traveling direction, where one of them faces an inner periphery section from an outer periphery section and the other faces the outer periphery section from the inner periphery section. <P>COPYRIGHT: (C)2004,JPO |
