信息时代的核心无疑是信息技术,而信息技术的核心则在于信息的处理与存储。当我们每天关注于CPU主频的不断提高、操作系统版本的不断升级以及计算机网络技术的日新月异的时候,我们或许不应该忽略这样一个事实,即无论信息处理技术多么的先进,我们都必须将信息存储于一定的媒体(或称“载体”)之上,信息和信息技术本身都需要依托于一定的存储媒体而存在。存储媒体的好坏是影响数字信息长期保存和读取的一大因素。因此要保证数字信息的长期存取,就必然涉及到存储媒体的选择问题。 目前,我国仅有一个国家标准《电子文件归档与 The core of the information age is undoubtedly information technology, and the core of information technology lies in the processing and storage of information. While we are constantly focusing on increasing CPU clock speeds, the escalating operating system version, and the advent of computer networking technology, we may not ignore the fact that no matter how advanced information processing technology we have to put information Stored in a certain media (or “carrier ”) above, information and information technology itself needs to rely on a certain storage media exist. The quality of storage media is a major factor affecting the long-term preservation and reading of digital information. Therefore, to ensure long-term access to digital information, it is bound to involve the choice of storage media. At present, our country has only one national standard "electronic file filing and
