<P>PROBLEM TO BE SOLVED: To provide a storage medium having sufficient reproduction durablity, a reproducing method and a recording method. <P>SOLUTION: A mixture of an organic metal complex single body and a plurality of cations and anions of an organic metal complex has excellent reproduction light durability. In an "L→H" type optical disk using a mixed dye, the reproduction durablity of one million times or more are attained in 0.4 mW reproducing laser power. Especially in an optical disk using a mixed dye of two of the cation and the anion of the organic metal complex and the organic metal complex single body, reproducing light durability of 1.5 million times or more is attained. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
