Easy three-step thorough cleaning of the optical drive internal parts

1. Cleaning of gear transmission equipment

Old-fashioned optical drives, such as the speed of 24x below the optical drive, a large part of the use of belt drive. Due to the expansion and contraction, belt transmission is more prone to failure. Optical drive compartment door in and out of the skid, stuck, and so on, mostly because the belt is too aging. In this case, replace the new belt. and gear drive of the optical drive is relatively easy to maintain, gear teeth or wear serious damage, as long as a new one on the line, if the use of a longer time, you can give the gear point lubricating oil, which can reduce the wear of gears, to a certain extent, can prolong the life of the optical drive. Note that when lubricating the gears and drive shafts, do not touch the bald components (preferably using solid lubricants, without liquid lubricants).

　　2. Cleaning of the laser head assembly

The general optical drive does not read the disk, or read the disk bad phenomenon is mostly caused by the laser head dust too much. Cleaning the laser head is the most troublesome part of the whole process of cleaning the optical drive. The bald lens is usually located next to the spindle motor and is a light blue mung bean-sized thing. This blue laser head lens is fixed on the elastic object, note that the wipe should not force too much, otherwise it will make the bald-headed offset.

A conditional friend can use a magnifying glass to see how much dust is on the bald lens before wiping the bald lens. Less, with a absorbent cotton sign lightly wipe a few can. If more, you can first wipe with a cotton swab, and then wash with a solution. The solution for scrubbing the optical drive preferably uses anhydrous ethanol with high purity, and some people think that ethanol dissolves the coating on the bald lens. In fact, the coating on the bald lens is composed of magnesium fluoride, magnesium fluoride film is the role of reducing refraction, increase transparency. While anhydrous ethanol does not dissolve magnesium fluoride at all, it is a bit exaggerated to use ethanol to clean the laser head lens and dissolve the organic coating.

On the cotton swab to talk about a little, medical large cotton swab above there are too many fibers, absolutely not. The smaller ones that are sold in supermarkets can be used. If you really can not find such a cotton swab, and laser head lens dust is not much, then we may also find a new cigarette, unplug the filter, ripped from the middle, remove the outer circle of paper to reveal the filter wire, folded well, and then you can use the filter on filters to wipe the bald lens.

　3. Adjust the laser head power

In the next or next side of the laser lens, there will generally be a green bean-sized potential regulator. It adjusts the power of the laser head by increasing or decreasing the resistance to change the strength of the current. Its shape is a bit like a screw cap, so it can be adjusted with a small screwdriver or a small screwdriver that repairs a clock. Adjust clockwise or counterclockwise to a 5-degree base. Each adjustment once the power to check the optical drive to read the effect, until satisfied. But remember not to adjust too much, power over the general will cause the laser head burned.

The computer CD-ROM is a very sensitive part, disassembly cleaning improper words, there will be some small problems, such as the inability to read the disc or Chuck, etc., so the user intends to clean the use of the optical drive will be more patience to spend a bit more careful oh.
