What is the reason why my computer optical drive keeps not reading discs?

If the optical drive on the computer is polluted by dust, then the laser beam it emits will be relatively weakened, resulting in a decrease in the fault tolerance of the optical drive, and the intensity of the laser beam required for normal reading can not be reached, and sometimes even the normal disc can not be read, even if it is read, it will continue to automatically reduce the speed. The solution to this problem is to clean the laser head. There are generally two ways to clean the laser head, one is automatic cleaning, and the other is manual cleaning.

The automatic cleaning method is simple, but the effect is not as good as manual cleaning, manual cleaning is more troublesome, but the effect is very good.

Let's explain the two separately:

1. Automatic cleaning: buy a special cleaning disk of the computer CD drive, (note, do not buy the kind of cleaning disk used by the VCD machine), put it in your optical drive, under Windows, use the CD player software in the attachment **This disk,**After finishing, take out the cleaning disk. At this point, your optical drive has been cleaned, you can check whether the optical drive's reading ability has improved, if it doesn't work, you can try to use manual cleaning.

2. Manual cleaning: (it is recommended to find a knowledgeable one) use a tool to open the shell of the optical drive, there is a small glass-like ball in the ** position of the optical drive, this is the laser head, use a clean cotton swab, dip it in a little alcohol, gently wipe it on the surface of the laser head, after wiping, after the alcohol evaporates and dries, cover the optical drive shell.

At this time, the ability of your optical drive to read the disk will definitely be greatly improved.

There is also a violent way, which is to disassemble the optical drive, and then look at a small screw under the bald head, and if you want to screw it a little left, it's OK.

What is the reason why my computer optical drive keeps not reading discs?”

Your computer CD-ROM drive is old"now"Not reading the disc is the reason.

If you change the optical drive, it won't take long to clean it (it's hard work).

The head is aging, you can try to clean it with alcohol.

Or because of long-term reading of pirated discs, the head of the optical drive has been damaged, and if that is the case, I suggest you replace it with a new one.

1. The bald head accumulates dust, which makes the ability to read the disc worse. If you know how to do this, remove the optical drive, turn it on, and wipe the laser head a few times with a medicated cotton ball dipped in anhydrous alcohol or distilled water (wipe in parallel, do not wipe in circles). Do not use detergent - it will form a film), dry for twenty minutes, and then put it on.

You can make the optical drive work for you for a while longer. Ordinary users do not have the ability to do it, and it may be difficult to recover it when disassembled and cleaned, so it is recommended to buy a disc that cleans the bald head to use, and generally buys it where the disc is sold.

2. If it is not used for a long time, the transmission mechanism and moving components of the optical drive lack lubrication, so that the speed becomes low or cannot be rotated. It could be that the laser mount slide shaft is out of oil or stuck. Clean the metal shaft and add some oil.

After you put the disc in, pay attention to whether there is a sound of rotation, or other abnormal sounds, and you can tell.

3. Aging of the laser head. You can increase the output power of the laser head, there is an adjustment screw behind the laser head card holder, slowly rotate about 15 degrees, if not, turn 15 degrees, and try repeatedly until you can read the film.

4. The driver of the optical drive is damaged or installed incorrectly. Usually Windows comes with a driver with an optical drive, and there is no need to add it separately. If the driver of the optical drive is not installed with its own driver, the optical drive will also be lost.

At this time, you can enter safe mode, delete the "cdrom" option in "Device Manager", and then restart the computer, let the system find the new hardware and reinstall the driver of the optical drive.

5. Pirated discs or platters are of poor quality to make the optical drive unreadable. The machine is designed for audio and video discs, and has good error correction and compatibility capabilities for almost *** discs; The optical drive is mainly used to read disc data, and the reading ability of video discs is of course not as strong as *** machine.

6. The disc reading performance of the optical drive is not good. This usually happens with a newly purchased assembled computer or a newly purchased optical drive. There is a loud "buzzing" sound when reading the disk, and after troubleshooting the optical drive, it is likely that there is a problem with the power supply. It is necessary to take it apart and check it.

1.Confirm if the disc is causing the problem.

1-1.Clean and inspect the disc for damage: Use a disc cleaner or a lint-free cloth to clean the disc of dust or dirt. If the surface of the disc is badly damaged, try replacing the disc to confirm.

Update the BIOS to the latest version and update to Windows Update

Enable and reinstall the driver in Device Manager.

2-1.Enter [Device Manager] in the Windows search bar, and then tap [Open].

2-2.Click on the triangle next to the [*** CD-ROM drive] device type. Right-click on [Undetectable Optical Drive] and select [Enable Device]. Check whether the optical drive can be detected.

If the [Enable device] option is not displayed, your optical drive is enabled, and please proceed to the next step.

2-3.Uninstall the driver of the optical drive. Right-click on [Undetectable Optical Drive] and click [Uninstall Device].

Please click Enter a description.

Please click Enter a description.

2-5.Restart your computer. After you restart your computer, the system will automatically install the drivers. Check whether the optical drive can be detected.

3.Use the Hardware & Device Troubleshooter.

3-1.Enter [Troubleshooting Settings] in the Windows search bar, and then tap [Open].

3-3.Follow the on-screen prompts and try to resolve the issue, if the drive is still detected after using the troubleshooter, proceed to the next step.

4.Restore your system through a system restore point.

If you have previously established a system restore point, or an automatic system restore point, try to restore the system to the restore point that was last since the last normal boot.

5.System Restore.

If all the troubleshooting steps have been completed but the question persists, perform a system restore after the backup.

Try to change to another disk, if the other disk can be read, it proves that it is the reason for the system disk. If you don't read it, it proves that the optical drive is not good, or it may be that the optical drive is weak in reading the disk, and if you can get it, take the optical drive and take the absorbent cotton to inspect the laser head. If you don't have absorbent cotton, wipe it with the filter of a cigarette.

The optical drive does not read the disk: on the optical drive and the disc two aspects of the problem: first, the optical drive.

Most of the problems of the optical drive are as follows: dirty or damaged optical head, laser power drop or defocus, poor error correction ability, faulty decoder board, disconnected data or power cable, or poor contact, etc. Any of these problems may result in not reading the disc or selecting the disc.

2. CD-ROMs. The problems of optical discs are as follows: disc quality problems (including the quality of blank discs and the quality of burning, whether the disc surface is damaged, etc.), disc deformation, disc format problems, etc.

Some plates are regionally restricted.

Suggestion: Try to find a few good disks that can be read normally on other optical drives. If you can't read it on your optical drive, you can rule out the disc problem, which is a problem with the optical drive; If some of them can be read, it's the disc drive.

If there is no effect after cleaning with a cleaning disc, it may be that the bald head is aging. If they can all be read, it's the problem with those discs. If it is a problem with the optical drive, this optical drive can be used, or you can consider changing the optical head or replacing it with a new machine.
