英国帝国化学工业公司最近声称,他们发明了一种新型的信息存贮介质——数字纸(digtzl paper)。数字纸与其它存贮介质相比,具有价格低、存贮密度高、存贮容量大及存贮速度快等优点,是一代很有发展前途的信息载体。数字纸是一种柔韧的光数据存贮介质。它由四层物质组成:即基层、反射层、光存贮层和保护层。基层是聚酯,具有柔韧性,因此可以将数字纸裁制成各种形状的信息记录载体。如带状、盘状、筒状等等。数字纸的记录和读取原理与激光唱片相类似,即激光照射在光存贮层上,由于光存贮层对激光特别敏感,经激光照射的地方形成凹槽而记录信息;读取信息时,凹槽露出反射层。反射
British Imperial Chemical Industries recently claimed that they invented a new type of information storage media - digtzl paper. Compared with other storage media, digital paper has the advantages of low price, high storage density, large storage capacity and fast storage speed. It is a very promising information carrier of this generation. Digital paper is a flexible optical data storage medium. It consists of four layers of material: the grassroots, reflective layer, optical storage layer and protective layer. The base layer is polyester, flexible and can therefore be used to cut digital paper into information record carriers of various shapes. Such as ribbons, plates, tubes and so on. The principle of recording and reading of digital paper is similar to that of a laser disc in that laser light is irradiated on an optical storage layer to record information by forming a groove where laser light is irradiated as a result of the optical storage layer being particularly sensitive to laser light; , The groove exposes the reflective layer. reflection
