清洗光驱（CD-ROM cleaner） Under normal circumstances. If you want to clean it: one is elementary: (this usually solves 30% of dust problems) Open the cover on the CD-ROM, observation of the object surface, whether there is a hazy feeling, this is because the dust accumulation in the lens surface, and affected by the surrounding humidity at deposition, blowing or hair dryer is not enough. Please use a clean cotton swab (preferably a cotton swab). Dont use any solvents. Just rub it gently. It must be light, light, and light. At this point, you can clearly see the surface of the sense of transparency. Finished, put the top cover. Two is advanced: (this generally can solve 80% dust problem) The laser head is used for a long time, the environment is very poor, the design of the head is defective and so on. Will cause light pollution, which is the same as that of the upper lens, but the light path is below the objective lens. Its a lot of trouble at the moment. It requires a lot of professional knowledge and great patience and carefulness. First remove the head shield, remove the objective assembly (objective lens, support, including focusing and tracing coils, etc.). Please mark the position before removal, including the location of each screw. After canceling the objective assembly, you can see the 45 degree half mirror under the vertical light path. This is the easiest place to pollute. Please find a very fine (about 1mm-2mm) plastic tag with a little cotton wool on the head, less, but it must be covered with a plastic label, not to allow the rod to have a chance to damage the mirror. This operation must be particularly light and extremely light. Since the space is only about 3mm, please slowly rotate the small swab to remove dust. You can look at it with a torch. The mirror will shine. At this time, you can use a watch blowing, blowing a few holes in the hole. Reinstall the objective assembly after completion. This is the key to success. Be sure to take good marks. Ensure
