    • A program length extending or shortening device for extending or shortening the program length in a digital video tape recorder of the image information compression recording method. The device comprises storage means for storing an image of a material video program reproduced and supplied from a predetermined recording medium by a reproducing device, and extending or shortening control means for extending or shortening the program length of the material video program to produce a target video program by skipping or reading duplicately the image of the material video program from the storage means in accordance with a program length extending or shortening ratio N based on the program lengths of the material video program and the target video program. According to the present invention, the program length can be freely extended or shortened using storage means of a small capacity while the recording device is being operated at a normal rate.

    • 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。
