四、磁鼓组件 磁鼓组件是录像机机心的核心部分,其质量水平和技术性能不仅直接影响录像、放像的图像质量和伴音质量,而且关系到录像机向多功能、高品位方向发展。 录像机记录和重放图像就是由磁鼓组件上的视频磁头将视频信号记录到磁带上或从磁带上感应出视频信号。为使图像清晰、稳定,要求磁鼓旋转工作时,必须保证视频磁头与基板具有准确的高度与角度,并为磁带边缘设置精确的导向面,
Fourth, the drum assembly Drum assembly is the core part of the video camera movement, the level of its quality and technical performance not only directly affect the recording, playback image quality and sound quality, but also to the video recorder to multi-functional, high quality direction. VCRs record and playback images by video heads on the drum kit video signals recorded to tape or tape from the induction of video signals. In order to make the image clear and stable, when the drum is required to rotate, it is necessary to ensure that the video head and the substrate have the exact height and angle, and an accurate guiding surface is set for the edge of the magnetic tape.
