录(放)像机工作时,磁头以每分钟1500转高速旋转,磁带上的氧化物碎屑和灰尘就会对磁头摩擦和碰触,使磁头变脏和磨损,令图像质量下降。所以,磁头必须清洗。目前,清洗磁头有干/湿式磁头清洗带;显像式磁头清洗带,具有清洗磁头功能的录像机等等。这些都是用清洗带去摩擦磁头,显然对磁头是有损害的。保护录像机磁头,一是要选用高质量的磁带;二是要使磁带表面清洁。前者是可以做到的,而后者因环境和磁带本身因素却难以保证。
Record (put) the camera work, the head at 1500 rpm high-speed rotation, the tape oxide debris and dust will be on the head friction and touch, the head soiled and worn, so that the image quality degradation. Therefore, the head must be cleaned. Currently, cleaning heads have dry / wet head cleaning belts; progressive head cleaning belts, video heads with cleaning heads, and the like. These are used to clean the head with the friction, it is clear that the head is damaged. Protection of video heads, one is to use high-quality tape; the second is to make the tape surface clean. The former can be done, while the latter is difficult to guarantee due to the environment and the tape itself.
