Solution of Computer optical drive not reading disk

Computer optical drive due to often read disk friction, as well as some other reasons, will appear can not read the disk, the following for you to explain the CD drive does not read the possible causes and solutions!

If an optical drive does not read the disk, we first add electricity and put a genuine disc to see if the panel lights flashing, there is no "Tatsu, Da, da" sound, if there is, then we can conclude that the laser head and the main bearing of the sensor is broken. Because when we put in a CD-ROM, the bald first need to go through the sensor positioning, if the sensor is broken, then the bald head will keep searching for, and thus appear "Tatsu, Tatsu, Tatsu" voice. If this is the case, we just open the enclosure of the optical drive, to LG CD-ROM, for example, the main bearing in the recessed place next to a pencil core thick 3MM long thin column, which is located in the relative position of the bald head of the white plastic sheet of the front end of the match. If it is not bonding, you can use glue or other objects carefully to the white plastic film front-end lengthened, the problem will be solved.

If the panel light is bright and there is no abnormal sound, then open the shell in the power to put on the CD-ROM, observation of the main motor work, if the main motor without action, we must first check the power supply of the main motor is normal, the motor transmission belt is slipping, fracture. State switch whether the switch is free, because if the switch is not in place, the main motor can not get start signal can not start. To determine whether the optical drive is faulty circuit or laser head failure, you can put a good quality of the genuine CD-ROM, should have the following actions occur:

1, Laser emitting Yang Liang (red), optical drive panel indicator light;

2, the laser head frame has the reset action (return to the spindle motor nearby);

3, the laser head is retrieved from the inner ring of the disc to the outer ring and then back to the motor near the spindle;

4, laser head focusing on the lens up and down focus on the search three times, spindle motor acceleration three times to find discs.

If the above action occurs, the laser tube is extinguished, the spindle motor is stopped, then the optical drive control circuit and the servo circuit is normal, it is possible that the laser head components are faulty. Otherwise, check that the optical drive control circuit and the servo circuit are normal.

For the DVD's laser head, there are generally two light-emitting tubes. If two light-emitting tubes are normal, the light should be pure red light, also known as the full light, you can read the normal CD, you can also read DVD disk. If the light color is darker and whiter, indicating that there is a bad light emitting tube, then the consequence is not to read the DVD disc or do not read the normal CD disc. If the laser head of the fault, then you will be miserable! If the optical drive is older, you can consider a new switch. Because the laser head is the most precise part of the optical drive, but also the most expensive part, the individual can not repair!

For LG DVD optical drive control circuit and servo circuit, if the main bearing does not turn, to check the bearing and the circuit board data Line (on the right) connection is intact, the circuit board connected to the drive chip between the circuit is smooth. If the bald-headed self-test issued a red light, but do not seek, then look at the control of the bald-headed stepper motor and circuit board connector (right) is connected to the link between the driver chip circuit is smooth. Finally check if the drive chip is damaged.

If everything is OK, still do not read the disk, please check the laser head to the circuit board is the data line loose? Use a multimeter to measure the last time we said the middle of the server (that big) chip is damaged!

Besides, the optical drive has a poor reading disk. For ordinary CD-ROM, the first to check the disc tray above the disc arm pressure is large enough, optical drive with the increase in time, the disc arm pressure to reduce, resulting in the disc, the disc in the optical drive skid, of course, it is difficult to read. Can be in the disc rotation gently press the disc arm, if there is improvement, you can conclude that the disc arm pressure is too small, not enough to clamp the disc, adjust the disc arm gently down or the disc arm of the small spring out of the root of the pull out of the elongated and then mounted on it. For LG DVDs, because it is the magnetic force between the main bearing and pressure to clamp the disc, so there is no such problem.

If you find dust on the bald head, for the CD-ROM, if you can use the skin tiger to make a few blows, and then use the lens paper or absorbent cotton to rub. Be careful not to use anhydrous alcohol to clean the optical drive's laser head. At present, many friends are accustomed to clean the laser head with anhydrous alcohol, but doing so will sometimes cause a lot of damage to the laser head. Different laser head, the material used is also different, for a part of the optical drive, the laser head objective part of the use of a material similar to plexiglass, if the use of alcohol to wipe it, alcohol will dissolve on its surface, so that it becomes opaque and completely damage the optical drive laser head. For the DVD, because of its good sealing performance, coupled with higher integration, so we just wipe the bald head lightly, do not go to wipe the mirror.

We all know that we can adjust the power to improve the optical drive reading capacity, the same applies to the DVD. In the case of LG DVD, there are two small adjusting knobs on the top of the data interface of the laser head, measured with a multimeter, the resistance in the 1100 Euro-1200 to adjust the power of the DVD-ROM, the resistance in 600 euro to adjust the CD-ROM laser power. Our aim is to increase the power by adjusting the small resistance. Different optical drives adjust the direction of rotation is not the same. First make a mark, the angle of each turn is not greater than five degrees, rotate once to test once, look for the best position. Pay attention to not blindly improve power, because the power is to sacrifice the life of the laser head premise, if not properly adjusted, it is likely to burn out the light-emitting tube, so the adjustment must be careful.

The last situation is that the focus is diffuse or not, and you can look at the bald drive it will emit red light, with a piece of paper on top of the bald head, to see the laser beam projection, should be cast in the bald head, a red round dot (very small), if irregular or not cast in the top, the general CD in, Do not recognize the Chuppan, or inexplicably admit it (not recognized is the Panel on the indicator light just flash, the optical drive is not moving), this bald head can also be adjusted. The probability of this situation is small, may be caused by some vibration of the optical drive. For LG DVDs, there is a small black screw on one side of the laser head near the white plastic sheet, which we can adjust to adjust the position of the beam. But this is the last resort, not to have to use it.

　　Maintenance method of computer CD-ROM disk failure

The light is driven to use the normal, after the reload can not read the plate. Performance for the indicator light, in and out of the warehouse normal, but is not read disk.

Start to think that the data line is not plugged in the good, so many times after the plug or not. Can not, remove the optical drive, placed in the enclosure external good power supply, data cable is able to read the disk. You cannot read the disk after loading the chassis. After taking out again all normal. I've tried it so many times. Suspect is a chassis problem, after careful examination, troubleshooting is a chassis failure problem. Puzzled by the solution.

Remove the CD-ROM drive, take the hand over and over to see, did not find any problems. In the spirit of DIY and their own knowledge of electronic fur of the work, carefully looking for clues. Once gently shook the power supply D-type plug, found a bit abnormal, as if a little noise, careful look and no broken traces. Another shake, or a little louder, so with tweezers one foot to pick, and finally in the yellow line of that foot found loose phenomenon. With a watch, it was broken. This broken foot is really absolutely broken, tin point outside intact, simply do not see, is the tin point inside broken, a shake can hear the sound, if not carefully shaken or with a table test at all can not see out.

The problem was found, and of course it was settled. So I plug it in with a soldering iron. Load the chassis, connect the power supply, data cable, put the CD, everything is OK.

　　Analysis:

The original friend of the chassis is horizontal, loaded into the optical drive and then plugged in a power from the top down, so that may have already broken feet are squeezed open. Broken foot is yellow line, it provides 12V voltage, due to the interruption caused the optical drive is not working properly. As for the normal access to the pallet, it should be because the motor of the tray is the power supply of the 5V electricity, not 12V, so no impact.

　　The computer is all right, but the optical drive can not read the disk and read the poor how to do?

　　The solution to the difference in the ability of optical drive not to read or read disk

The optical drive does not read the disk, that is, put any disc can not be recognized, which is a relatively serious failure. caused by the optical drive can not read the disk is a lot of reasons, many of the optical drive mechanical part of the failure, such as may be the transmission mechanism is too dirty or bad lubrication. In addition, please check the CD-ROM device is too dirty or serious wear, too dirty words will not be able to hold the disc. If it is mechanical failure caused by the disk, you can try to handle, such as the CD-ROM related parts thoroughly cleaned. And for electrical reasons, such as optical drive spindle controller or laser head damage caused by the failure to read the disk, the individual can not handle, this situation will only send professional maintenance point maintenance.

Many optical drives in the use of a period of time, before the normal read out of the disk can not read, read disk ability to change the optical drive is the most common fault, generally speaking is the problem of laser head. First please check the Bald object surface is very dirty, you can use the Tiger to make a few blows, and then use the lens paper stained with some anhydrous alcohol cleaning. If still not, we need to adjust the power of the laser head, different brands of optical drive regulator position is different, but most of the head side of the laser, in the adjustment before the original position must be remembered, if not back again, first clockwise rotation, as long as a little bit on the line, if the invalid is reversed, and then counterclockwise rotation a little more, Adjust must be patient, do not adjust too much at a time. If the effect is not good, you can also try to adjust the angle of the laser head.

If the system can not find the optical drive, you should first notice whether the optical drive is detected at post, if the self-test is not found, it may be because the optical drive itself has a serious fault, incorrect installation or data line problems, you may pass the "replacement method" to confirm. If the optical drive can be found in the self-test process, but not found after entering the operating system, the reason is generally related to software. Under normal conditions, the optical drive does not require additional drivers to be installed under Windows. However, in some cases, such as infected with the virus, or improper installation of the motherboard driver may cause the loss of the optical drive, please check the virus, and reload the motherboard with its own drive.

The optical drive may not be found or the IDE controller port is occupied, and you can go into Safe mode to remove the IDE controller, and after restarting, you may be able to retrieve your optical drive. If you still have problems, you can add real-mode CD-ROM drivers in Config.sys and Autoexec.bat to temporarily emergency.

　　Computer optical drive does not read disk?

Can you feel the motor moving inside? If not, it is a hardware failure, if you can feel the move you will see if the disc is not a problem, if not to open the chassis to see if the data line is plugged in.

This should be a hardware problem, you open the chassis to check the power cable of the optical drive data cable is not connected, if all connected, and then check the Blos to disable the optical drive. If you don't have the above 2 questions, the CD drive is broken. need to buy again.

　　Other attempts:

1. Try the other discs to see if they are not possible

2. Check whether it is a CD-ROM, but you put the DVD disc in, is not a good

3. If not yet, no warranty will go to the warranty

First check my computer to show the CD drive letter does not, if not, you have to modify the registry to make the optical drive work.

Second, all of the disk is not read, that is the optical drive of the laser head aging, can be adjusted by adjusting the internal resistance of the optical drive recovery.

Finally, individual platters cannot be read, make sure the CD drive is not read DVD, otherwise the disc is broken.

　　If your operating system is windows7 and the CD-ROM is placed in the optical drive to see the name and information of the disc, you cannot right-click or double-click to open it.

　　Here's how to fix it:

Run Registry Editor "regedit" to expand the following location:
