自从计算机技术高度发展后,人们纷纷采用电磁方法来处理信息,然而今天绝大多数信息都不是存储在磁性载体上,仍然是以纸质文献、缩微胶卷、照片,唱片和电影等形式出现.这是因为磁性载体缺少一种兼容性,这些信息不适宜存储在磁性载体中,无法形成整体化信息系统。由于不能采用计算机存取各种资料,影响了文献管理效率。要构成整体化的信息系统,就需要一种能兼容各种信息的介质.激光光盘就是人们正在追
Since the advent of computer technology, people have used electromagnetic methods to process information. However, most of today’s information is not stored on magnetic carriers, and still appears in the form of paper documents, microfilms, photographs, records and movies. Because of the lack of a compatible magnetic carrier, this information is not suitable for storage in a magnetic carrier, can not form a holistic information system. Because can not use the computer to access a variety of information, affecting the efficiency of document management. To form a holistic information system, you need a media that is compatible with all kinds of information. Laser discs are what people are chasing
