<P>PROBLEM TO BE SOLVED: To record information containing individually independent items in a first recording face interposed between a first sheet and a second sheet and in a second recording face positioned on the surface of the second sheet in the state that both sheets are laminated together and upgrade the opacifying properties of the information recorded on the first recording face. <P>SOLUTION: This recording medium is constituted in such a way that a visible image is formed on the first recording face 15 without adversely affecting the second recording face 23 in response to the recording performance by a first recording means from the face side of the second sheet 20 and a visible image is formed on the second recording face 23 without adversely affecting the first recording face 15 in response to the recording performance by a second recording means from the face side of the second sheet 20. At a corresponding position to the first recording face 15 of the second sheet 20, a lightproof part(a lightproof layer) 22 is formed so that the lightproof part(the lightproof layer) 22 shields light, even when the second sheet 20 is thin and the first sheet 10 is seen through and consequently, information recorded in the first recording face 15 can be read. <P>COPYRIGHT: (C)2004,JPO |
