本文介绍了长期贮存视频磁带所必需的许多重要知识,包括干燥凉爽的环境和录象机的合理保养。同时,也介绍了正确的卷绕技术,即对磁带的缺陷、合适的缠绕张力及每隔多久应将磁带重绕一次等均作了详细说明。而且还给出了为延长磁带的寿命进行测试的几条建议和磁带受热或浸水后应如何处理的忠告。本文附有一簇恒定湿度曲线图以表明磁带和VTR的环境限制。本文的内容均是根据实践中的经验、理论上的研究及加速试验结果获得的。遵照该文中的建议和忠告,可以使录制在磁带上的信息保存时间大为延长,但是并不能保证这些信息可以永久地被贮存下来。
This article describes many of the important pieces of knowledge necessary for long-term storage of video tapes, including dry, cool environments and proper care for video recorders. At the same time, also introduced the right winding technology, that is, the defects of the tape, the appropriate winding tension and how often the tape should be rewound once were described in detail. It also gives a few suggestions for testing tapes to extend the life of tapes and advice on how to handle tapes after they have been heated or flooded. This document is accompanied by a cluster of constant-humidity graphs to demonstrate the environmental limitations of tapes and VTRs. The contents of this article are based on practical experience, theoretical research and accelerated test results obtained. By following the advice and advice in this article, the information recorded on the tape can be stored for a substantial period of time, but there is no guarantee that the information will be stored permanently.
