PURPOSE:To record a high-density information by using a specific cyanine organic dye in a recording layer. CONSTITUTION:An organic dye recording layer 2, a reflecting layer 3 and a resin protecting film 4 are provided on a light transmitting base plate 1 to form a light recording medium. At this time, the cyanine organic dye expressed by the formula I (wherein X<-> represents ClO<->4 and I<->, R and R' represents CH3, C2H5 and C3H7) is used in the light recording layer. By using such a dye, is obtained light recording medium on which the information higher in density can be recorded using the laser of a short wavelength. |
