随着录象磁带性能的提高,1/2英寸高密度记录方式已经能够录放色彩鲜明的图象,录象机正向着高性能多功能化发展。但是为了增长记录时间,走带速度就相应降低。如果仍然用固定磁头来录放音频信号,其频率特性会受到直接的影响。再加上抖晃等因素,
With the improvement of video tape performance, 1/2 inch high-density recording method has been able to record colorful images, video recorders are moving towards high-performance multi-functional development. However, in order to increase the recording time, the traveling speed is correspondingly reduced. If you still use a fixed head to record audio signals, its frequency characteristics will be directly affected. Coupled with shaking and other factors,
