激光唱片(简称CD片)是激光唱机的声源,它通常由聚碳酸塑料制成的,表面镀膜呈银色或金色。在日常使用中,有时因使用或保管不妥,造成激光唱片变形翘曲,旋转时激光唱片不能保持水平状态,影响激光束扫描,引起放音效果变差。若发现这种现象,可取两块比激光唱片销大些的玻璃,将激光唱片夹在中间,并用夹子夹紧玻璃。另准备一盆温度约为50C的清水,将激光唱片随同玻璃一起浸入水中,放置10
CD (CD film) is the sound source of a CD player, it is usually made of polycarbonate, the surface coating is silver or gold. In daily use, sometimes due to improper use or storage, resulting in warping deformation of the disc, rotating disc can not be kept in a horizontal state, affecting the laser beam scanning, resulting in poor sound reproduction. If you find this phenomenon, it may be desirable to sell two larger than the laser disc glass, the laser disc in the middle of the folder, and clamp the glass with a clip. Another preparation of a basin of water temperature is about 50C, the laser disc along with the glass immersed in water, place 10
