<P>PROBLEM TO BE SOLVED: To provide a storage medium with the adequate number of times of durable reproduction, a reproducing method, and a recording method. <P>SOLUTION: A mixture of an organic metal complex single body and a plurality of organic metal complex cation-anions has excellent reproduction light durability. In an "L→H" type optical disk using a mixed dye, the number of durable reproduction of 1,000,000 times or more is achieved with a reproduction laser power of 0.4 mW. In particular, with a mixed dye of two kinds of the organic metal complex cation-anions and the organic metal complex single body, a reproduction light durability of 1,500,000 times or more is achieved. <P>COPYRIGHT: (C)2011,JPO&INPIT |
