东芝基础技术研究所成功研制了一种新型的色素有机分子光盘,可使信息记录密度提高到DVD的200倍。该项技术是把色素的分子加工成极微细的点状结构,用光纤检测出这种分子的发光状态。与传统的光存储器相比,可以更准确地读出和写入信号。这是开发10~(12)(兆兆)级存储器的基础技术,该技术可望在2010年达到实用水平。东芝谋求通过这一研究成果,掌握DVD之后新光盘行业的领导权。 色素分子光盘是把色素原料的有机分子蒸发到硅衬底上而形成记录媒体。有机分子依靠分子本身所具有的凝聚力而凝固成直径约为10nm的极微细点状,这就构成了记录的最小单位。若该光盘的直径为12厘米,则可存储的信息量相当于200张 Toshiba Institute of Basic Technology has successfully developed a new type of dye organic molecular CD-ROM, the information recording density can be increased to 200 times the DVD. The technology is the pigment molecules processed into very fine point-like structure, with the optical fiber to detect the light-emitting state of such molecules. Compared with the traditional optical memory, you can read and write signals more accurately. This is the basic technology for developing 10 ~ (12) terabytes of memory, which is expected to reach the practical level by 2010. Toshiba seeks to pass the research results, master DVD after the new CD-ROM industry leadership. Pigment Molecules An optical disc is formed by evaporating organic molecules of a pigment material onto a silicon substrate to form a recording medium. Organic molecules relying on the molecules themselves have the cohesion and solidification into a very small diameter of about 10nm dot, which constitutes the smallest unit of record. If the diameter of the disc is 12 cm, the amount of information that can be stored is equivalent to 200
