(一)故障现象重放图像上有扫帚状亮点拖尾,此外,图像上还产生随机白线,而且图像局部扭曲,彩色边缘不齐,有拉毛现象。(二)故障分析重放图像上有扫帚状亮点拖尾及产生随机白线,这种故障多数由磁鼓的静电干扰引起。磁鼓在运转和与磁带的摩擦过程中很易产生静电,积存在磁鼓上的静电常会发生随机的放电现象,放电火花电流便形成
(A) failure phenomenon replay image broom-like highlights trailing, in addition, the image also produces a random white line, and the image is partially distorted, the color edge is missing, with the phenomenon of hair. (B) Analysis of the failure There are broom-like highlights on the replay image tailing and generate random white lines, most of this failure caused by the drum electrostatic interference. Drum in operation and friction with the tape is very easy to produce static electricity, static electricity accumulated on the drum often random discharge phenomenon, the discharge spark current will be formed
