光盘信息存储利用了高功率写入激光使记录介质在写入处光学性质发生变化的原理,信息写入的过程就是“标记”形成的过程,标记形成的微观变化称为写入机构。约20年前 Carlson 等人就指出,激光写入可引起薄膜光学性质的变化。碲薄膜和碲合金薄膜很早就被作为可擦除和不可擦除记录介质得到详细的研究。Ovshinsky 等人研究了碲合金材料作为可擦除介质的标记形成机构,他们认为标记的形成是非晶态与晶态之间
The optical disc information storage utilizes the principle of high-power writing laser to change the optical property of the recording medium at the writing position. The process of writing information is the process of “marking”, and the microscopic change of the marking is called the writing mechanism. About 20 years ago Carlson et al. Pointed out that laser writing can cause changes in the optical properties of the film. Tellurium and tellurium alloy thin films have long been used as erasable and non-erasable recording media to get detailed studies. Ovshinsky et al. Studied the tellurium alloy as a marker-forming mechanism for erasable media, in the opinion that the formation of the mark is between amorphous and crystalline states
