录象机(包括放像机)在重放过程中,当画面上出现雪花和噪声点时,可能是磁头脏了。 所谓“磁头脏了”是指录象机视频磁头面上堆积了尘埃和磁粉等脏物。这些脏物使高速旋转的磁头不能紧贴磁带表面,导致录象机不能正常记录和重放。那么,如何清洗录象机的磁头呢?下面介绍三种方法,供参考。 一、麂皮清洗法。到商店购买一条扁平清洁棒(也可用牙刷柄制作),将麂皮(也称化学皮)卷贴在清洁棒的一端,然后蘸上少许清洁剂(不要太多,麂皮湿润即可),如氟利昂、四氯化碳、无水酒精、甲醇等。用右手握住清洁棒的另一端,小心靠近磁鼓,将麂皮平面轻轻贴在磁头上,再用左手食指缓缓转动上磁鼓,反复清洗,直至洁净为止。
VCRs (Including Players) During playback, when a snowflake and noise point appears on the screen, the head may be dirty. The so-called “head dirty” refers to the head of video recorders stacked dust and magnetic particles and other dirt. These so that the high-speed rotation of the head can not be close to the tape surface, resulting in the video recorder can not be properly recorded and replayed. So, how to clean the head of the video recorder? Here are three methods for reference. First, suede cleaning method. Buy a flat clean stick (which can also be made with a toothbrush handle) at the store, roll a suede (also known as a chemical patch) on one end of the cleaning rod, and then apply a little detergent (not too much, suede moist) Such as Freon, carbon tetrachloride, anhydrous alcohol, methanol and so on. Hold the other end of the cleaning rod with your right hand and be careful near the drum. Put the suede surface gently on the magnetic head and slowly rotate the upper drum with your left index finger until the surface is clean.
