摘要
本文就激光电视唱片的录制;激光电视唱片的放象原理;伺服跟踪等几个方面详细地阐述了激光电视唱片系统的原理.电视唱片(俗称光盘)是目前信息存贮密度最高的介质,其用途广泛到可以存贮几乎所有的信息表达形式,如照片、活动图象、语言、文字、数字信息、模拟信息等.而且便于与计算机及计算机网络系统,现代通信设备及通信方式接口,拥有巨大发展潜力.随着光盘技术日益发展,其应用前景将更为可观.
This paper describes the principle of a laster videodisc system in detail in the aspects of the recording, replaying and servo. The laster videodisc is the medium with the largest storage density of information at present. It can be used to store almost all information expressions, such as photo, mobile pictures, language, literal, digital information and analog information and it is convenient to interface with computers, the computer network modern communications. It has great potentialities and a considerable future with the development of the videodisc technology.
