电视唱片是世界上七十年代后期新兴起的一种最新颖的电视录像技术。所谓电视唱片就是用一张同普通的录音唱片相同的录像唱片,通过放像机由一般的电视机接收,就能看到“自备节目电视”(国外称:Video Package)。它不仅方便地用于家庭观看有选择性的文艺节目,而且更主要可以用于图书、情报、档案的资料、银行、医院、教学和科研的图片文字数据记录储存及电子计算机数字储存等。从技术性能、成本、应用及发展潜力来看,电视唱片处于极其优越的地位。它的特点:①图像记录质量好②储存密度大③使用方便④寿命长⑤成本低⑥用途广。 本文较概括地综述了电视唱片的发展动态。还以激光电视唱片为例概述了其原理,特点和应用。关于电视唱片用的特殊金属材料也作了简要介绍。
Television recordings are one of the most innovative television video technologies emerging in the late 1970s. The so-called TV album uses the same video recording as an ordinary recording, and is received by an ordinary television through a video player. Then, the “self-produced television program” (“Video Package” abroad) can be seen. It is not only convenient for families to watch selective art programs, but also can be mainly used for books, information, archives, banking, hospitals, teaching and scientific research, image and text data storage and electronic computer digital storage. Judging from the technical performance, cost, application and development potential, TV recordings are in an extremely advantageous position. Its features: 1 good image recording quality 2 large storage density 3 easy to use 4 long life 5 low cost 6 wide use. This article gives a more general overview of the development of television recordings. The principle, characteristics and applications of laser television recordings are also outlined. The special metal materials used in television recordings are also briefly introduced.
