自从1948年美国哥伦比亚在纽约进行黑白电视广播以来,人们就开始设想利用磁记录方式来保存电视节目。1950年后安培克斯公司首先投入研制旋转磁头记录器,1956年四磁头横扫黑白录象机达到了实用阶段以后,各种各样的录象机和彩色录象机随着磁头、磁带、伺服、调制解调电路技术的进展也越来越完善。它的应用范围也不断地向生产、科研、国防建设等领域扩展。现从下述几个方面对当前国外旋转磁头记录器概况作个粗略的介绍。
Since the United States Columbia in 1948 in New York for black and white television broadcasting, people began to envisage the use of magnetic recording to save the TV shows. After 1950 Ampex company first put into the development of rotary head recorders, 1956 quadruple head to sweep the black and white video recorders reached a practical stage after a wide range of video recorders and color video recorders with head, tape, servo , Modulation and demodulation circuit technology is also progressing more and more perfect. Its scope of application is also constantly expanding to the fields of production, scientific research and national defense construction. Now from the following aspects of the current foreign rotating head recorder profile for a rough introduction.
