PROBLEM TO BE SOLVED: To provide a storage medium using an organic pigment material with which recording/reproduction can be performed with light of a wavelength of 620 nm or less, and to provide a recording method and recording device using the storage medium.SOLUTION: A light absorption rate is drastically decreased with light of a wavelength shorter than 620 nm due to the effect of absorption spectral characteristics of a conventional organic pigment material, and recording sensitivity is decreased. By using an "L→H" organic pigment recording material which has a reflection rate higher in a recorded portion (a recording mark) than in an unrecorded portion, the recording mark utilizing the decoloration effect due to separation of electronic bonds is formed, thereby requiring no substrate deformation and enhancing the recording sensitivity. |
