    • An optical information storage medium having small jitter value and high recording sensitivity. The optical information storage medium has a transparent pregrooved substrate having thereon a dye recording layer, in which information can be recorded by irradiation with a laser, and a light-reflective layer on the dye recording layer, which is made of a metal. The dye recording layer contains a dye A, which has a maximum absorption wavelength in a 400 to 700 nm range, and a dye B, which has a maximum absorption wavelength 3 to 50 nm longer than that of the dye A. A sensitivity ratio Q between the dye A and the dye B, which is represented by the following equation, is from 0.20 to 0.55: Q=(PA−PB)/PA where PA represents optimum recording power for the dye A and PB represents optimum recording power for the dye B.
    • 具有小抖动值和高记录灵敏度的光学信息存储介质。 光学信息存储介质具有透明预浸渍基板,其上具有染料记录层,其中可以通过激光照射来记录信息,以及在由金属制成的染料记录层上的光反射层。 染料记录层含有在400〜700nm范围内具有最大吸收波长的染料A和比染料A长3〜50nm的最大吸收波长的染料B.灵敏度比Q 在染料A和染料B之间,由下式表示,为0.20至0.55:其中PA表示染料A的最佳记录功率,PB表示染料B的最佳记录功率。
