摘要： The optical disk writing system disclosed is one in which a data written on an optical data writing medium is verified essentially simultaneously with the writing on the medium. The written data is verified by detecting a timing of the light irradiated on the medium and by measuring return light doses at a rise and a fall of the light irradiated on the medium and comparing the doses thereof with predetermined reference values. The medium used is one which uses a phase transition reversible between a crystal state and an amorphous state for writing/reading/erasing of data on a data writing film and includes, a first protective film (122), a phase transition type data writing film (123), a second protective film (124), a reflection film (125) formed in this order on a transparent substrate (121). The thickness of the first protective film is set such that, of three reflectivities of the data writing film respectively in crystal, amorphous and melted states, the reflectivity in the crystal state and the reflectivity in the melted state are made different from each other, and the reflectivity in the amorphous state and the reflectivity in the melted state are made different from each other. A high speed writing operation can be carried out and an overwrite operation can be completed in one time disk rotation.

摘要翻译：该游离缺失光盘写入系统盘是一种在其中写在光学数据写入介质的数据与媒体上的文字验证基本上同时。所写入的数据是通过检测照射在介质上的光的定时，并通过在上升并照射在所述介质上的光的下降测量返回光的剂量，并与预定的基准值比较其剂量验证。使用的培养基是一个其使用相转变的可逆结晶状态之间以及用于写/读/数据的上一个数据写入膜擦除非晶状态，并且包括一第一保护膜（122），相变型的数据写入电影（123），第二保护膜（124），以该顺序形成在透明基板（121）上的反射膜（125）。所述第一保护膜的厚度被设定的是，分别在晶体，无定形和熔融状态的数据写入电影三个反射率，在晶体状态和熔融状态的反射率的反射率是由从不同海誓山盟搜索，并在非晶状态和熔融状态的反射率的反射率是由从不同海誓山盟。一个高速写入手术可以进行，覆盖手术可一次盘旋转完成。
