How to repair a CD-DVD drive yourself?
This is a little information with pictures about how you can chew a CD-DVD, and not a Blu-Ray drive, without going to the expensive assistance of fakivtsi. There are a number of reasons that often accumulate and can lead to repeated or frequent failure of the drive. These reasons can be resolved not by repair, but rather by technical maintenance of the CD-DVD-ROM and, in general, can be done by the user, as beginners do with electronic equipment.

Most often the reasons why the drive fails.
- Worn drive belt (belt).
- Greater friction on the mechanism.
- Cloudiness of the laser lens.
- Reduced laser CCD.
To eliminate any of these reasons, it is necessary to disassemble the drive frequently. The design of the drives may change, so the original images cannot be captured at all.
For preventive work, we need available tools, materials and accessories. website
- Stationery violin.
- The twist is cross-like.
- Penzel of medium size.
- Calico (bavovnyana fabric).
- Silicone oil SI-130.
- Pasik.
- Serverette, what to clean.
- Thin twist.
- Tweezers.
Let's start. The cables are connected to the drive and the mounting screws are screwed on. The drive can be removed from the system unit case.
Rozbirannya.
The disassembly of any CD-DVD drive begins with the hanging tray. To hang the tray, you first need to prepare a simple device using a paper clip.
Carefully, by inserting the end of a paper clip into the technological hole on the front panel of the drive, we wind the part of the mechanism that indicates the blocking of the tray. The detail is located opposite the opening. We press on it and the tray hangs slightly. Now you can twist the yoga with your fingers.
The clamps are pressed to secure the front panel to the drive. We press out one of the bolts from the beginning.
Then, we press out the bolt that is located in the lower part of the drive, and another permanent bolt.
The front panel hangs, the screws with cross-like droplets are unscrewed, and the metal casing panel is removed.
We press the bolts and secure the tray under the main mechanism.
We carefully clean the mechanism of the saw and the beam with the help of a foam tool. If the old oil is very cloudy, then we remove it with additional calico and apply new oil.
We are replacing the old beanie with a new one. After that, we wipe the belt and the inner surfaces of the pulleys with a cleaning cloth or calico soaked in alcohol.
We wipe the laser lens with a servet to clean it. If the axles are on the upper surface of the lens, you may not be able to see it with an unbroken eye, otherwise it may be present there.
If the drive is already old or it is clear that there are a lot of disks recorded on it and in which case there is a problem with reading or writing, you can try increasing the laser beam. This delicate operation will require patience and may take up to an hour. Do not start this procedure if your drive simply does not read a number of old disks or disks recorded on other people's drives. This may be influenced by a lot of different factors and the size of the laser beam here on the 38th place.
Adjust the laser beam as quickly as possible if the drive is in a pressurized state.
To run the drive without the front panel cover, you will need to remove the front panel of the disc tray.
Here, on the carriage with a laser installed, there is a small-sized potentiometer, the position of the motor of which indicates the laser beam. The loosening of this potentiometer is contained in the design of the drive.
First, turn the screw downwards, making sure to seal the position of the slot, so that the point in the middle is aligned, so that you can turn it in the cob position at different times.
By turning the screw 10-15 degrees first to one, and then to the other, you can immediately check the readability of any program, for example, Nero DiscSpeed.
It is important to check the information on certain types of media, for example, CD-R and CD-RW or DVD+R, DVD+RW, DVD-R, DVD-RW, etc. Melodiously, it’s not obligatory to check all the types of noses that you’re looking for, but you don’t want to change the ones that you spend the whole hour admiring.
There are many universal drives, which require compromised drives and therefore often some types of disks are easier to read, and some are harder. For example, by increasing the laser beam, you can prevent the CD-R from being perfectly readable and render half of the CD-RW unreadable.
Folding does not create any difficulties, except for one moment. When inserting the tray into the locking mechanism, it is necessary to engage the hinge lock of the locking mechanism with the guide groove located in the lower part of the tray.
When you apply springs, you will need to first pull the tray straight from the bottom, fix the belt in the correct position, use a pair of tweezers or another similar tool. In the photo, the position of the pommel is fixed behind the sewing aid.
How to vibrate correctly for repairing the CD-DVD drive.
If you have a completely ordered, completely random, small set of beads of different diameters, then you just need to select a similar copy. If there is no such set, then you will have to buy a beanie.
And although the era of video and audio tape recorders has passed, on all radio markets you can still add hummies to the assortment.
When purchasing a beanie, you need to pay close attention to a number of parameters, such as: girth, diameter, spring, and the strength of vulcanization of gum, depending on the type of preparation.
The cut of the bean can be determined by eye, so the likelihood of you being able to find a bean that is strictly consistent with the cut is small.
The diameter of the bean can be determined by pressing the old bean to the new one and rolling so that the diameter of the new one is slightly smaller than the old one.
The brilliance can be seen at another improvised stand, as if it were a small thing.
I really check the power of the pasik on a pillbox without any dynamometers.
The strength of vulcanization of gum can be determined by the color and tactile sensations. The color of the “wrong” gum is deep black, and the surface is smooth with a high texture, which makes it stand out. In this case, the “correct” gum has a little gray tint and a mostly matte surface.
Also, the strength of gum vulcanization can be determined by the hour of renewal of the output size. To make the dough, you need to strongly stretch the dough with your fingers and very quickly throw it flat onto a flat surface. The more swedish the pasik takes the size of a cob, the more its fruit is yummy. As you can note, as the diameter of the bean changes, so that it is not noticeable, then such a bead will not last long and, better yet, will not be worn out. However, it is not a fact that you will find a high-yield pasik at the market, or just the one you need. Therefore, through the marriage of the best one, you can buy those that are corrected for diameter, webbing and springiness.
And so, all these parameters depend on the power of the bean. When you choose your bean, you need to vouch them. If the waistband of the beanie is smaller, then it is necessary to choose a beanie that is shorter and more appropriate. If the vulcanization strength is low, it is necessary to choose either a slightly larger girder or a slightly smaller diameter.
If the bead is tensioned too much, it can lead to jamming or premature wear of the disc tightening mechanism. If the belt is too loosely tensioned, you may be able to remove it from the engine pulley.
Since there are a number of beekeepers close to the authorities on the market, it is better to immediately buy a number of different ones in order to select the most suitable one at home. The price for a CD-DVD drive can range from $0.3 to $0.7.
Close to those.
Today's chicken comora gave us another piece of information to track the inner world - a drive for CD-ROM. We already know the theory about this device, but anyone who has forgotten it can read it. And I'm looking for screws, wire cutters and pliers.
Also: the axle is a marvel of Japanese technology, the warranty on it ended in 2000, but I’m not surprised that this car is still alive. But technology is not in place, and its slot in the computer has long been occupied by CD-ROM, and then by DVD. Without rubbing, insert the pin into the technological hole to tighten the disk drive. (Did you know how you can remove a disc from a CD-ROM on a connected computer?). It’s still working. Well, let's see.
We first unscrew the bolts on the plaque body and remove it. Bachimo drive the disk at the center. When you press the disc with your hand in the middle, the drive rises, connecting with the center of the disc. Let's take a look at the plastic "cavi stand." You can see the mechanism that ensures the disk is bent. This is an engine (not visible on the front photo, there are fragments of storage under the body), on its axis there is a small gear. Other gears create a classic gearbox, changing the fluidity of the hanging panel. The outermost gear enters the geared teeth on the disc selector panel and hangs or pushes back. The force that lifts the mechanism for wrapping the disk and reading the information is transmitted.
Distant mover - ensures the positioning of the element, which means it is on the required track. At the lower part of the structure, the developers placed a board with electronics. The motor for hanging the panel is soldered directly onto it.
I'm amazed at how the engine is used to turn the disk. Yeah, old knowy. I'm re-establishing the engine and the rotor and stator. The entire coil of electromagnets is fixed, and the body with a ring-shaped permanent magnet rotates around it. They tried, they tried the same thing at the Winchester, but it’s all the same - it’s miraculous.
The details are becoming smaller and the process is becoming more and more tedious. The axis and the head itself, which reads. The lens is molded to a plastic lens right up to the disk. The suspension arm is mounted on spring rods, and an electromagnet coil is wound around it. There are also two miniature, but strong permanent magnets. It looks like this system is focusing on me.
We remove the lens and remove the glued magnets. What's under the lens? There is a small mirror, rotated at 45 degrees and rotated at the side of the crystal. It seems that the LED that emits the pulse and the photodiode that reads the pulse are in the same package. Well, the sense is that it’s absolutely clear that the focusing system will be forgiven.
Well, okay, that’s all. What kind of dry surplus do we have there? A pair of motors suitable for the production of some kind of electric machine (the positioning motor hangs, the fragments are powered in the classical way - through two darts. The oblique disk of the motor is controlled electronically from the main board, which is a pity - hardly need further), a bunch of loose bolts , a bunch of plastic gears, a pair of strong magnets. Another evening was spent with great interest. Why else would you smoke like this?
As I wrote earlier in other articles, the biggest problem for a computer is saw. She goes as far as she can in such great numbers that at times she simply marvels. DVD drive for optical discs is not a problem.
The saw, if the device is not cleaned, flows onto the robotic tray drive, reduces the accuracy of the laser mechanism and flows onto the robotic squeezing mechanism. The DVD drive must be cleaned at least once in a while. Optimally – once for lunch.
For cleaning and maintenance of the DVD drive you will need oil, cotton swabs and alcohol. After removing the DVD drive from the system unit, you need to remove its front panel. We need to hang the tray in front of the drive. Try to get help from any long or thin object (heads, violins, 3 cm long pieces of clothing).
There is a small opening on the front panel of any DVD drive (item 2 in the bottom photo). Behind it (on the inside of the panel) there is a mechanism for manually opening the tray. It is necessary to press this mechanism through the opening with slight force and the tray to hang out 1-2 centimeters, after which it can be pulled out completely by hand.
Then you need to remove the sawtooth cap from the tray. To do this, turn the drive over and use your fingers to pry the lid open and pull it down. There are usually two clamps on the lid (item 1 in the bottom photo) and two straight ones, on which the lid rubs. It goes without any special zusil.
Then you need to press in the clamps of the front panel. As a rule, there are either four (two on the bottom, two on the sides), or five (two on the sides, three on the bottom). After removing the front panel, the bolts (4 or 5 pieces) on the bottom cover of the DVD drive are tightened and the cover is removed.
Then you need to take the DVD drive by the top cover and shake it a little. The plastic drive mechanism falls out of the top cover (dazzling photo below). After removing the covers, the optical disc tray is removed. It hangs until it stops, then the latches are pulled out, placed on the back of the tray along the corners (amazing photo below) and the tray is pulled out.
All parts from the DVD drive have been removed and you can proceed with cleaning. The main part of the DVD drive housing has a lot of grooves, grooves and corners. It is imperative to blow out the saw for proper cleaning. The thickness of the back wall or the grooves in the tray's movement may cause the tray to stop opening (closing).
The tray collapses behind the help of a motor, which is powered by a gum belt. You need to lift the bean carefully so as not to stretch it. In the future, the mechanical robot of the tray drive will lie down. Before speaking, problems often arise with the tray after three (more than two years) operation without maintenance. The blade is directly filled with saws and the tray is not pushed through in the extreme position, and then the belt is stretched through those that the drive mechanism cannot open the tray due to the incorrect position of the tray.
Next to the bead, the mechanical cleaning fee is removed (1 or 2 insertions). It is also important to be careful not to damage the cable of the motor, which is located next to the main board. On inexpensive models, the cables may appear to be tenacious or poorly soldered. Apparently I drank from the mechanics with a soft brush or from both sides (burn from the bottom). Ideally, you should go over each DVD drive first with a brush, then blow it off (for example, with a humic bulb, which is sold in any pharmacy).
After everything has been consumed from the device drive housing, the humic parts are degreased with alcohol and the old lubricant is removed from the surfaces (until the moment that there is a fine saw and a mixture with a small amount of lubricant that is lost).
First of all, there are loose mechanical parts that need to be rubbed, brushed with a small (meager) amount of oil, just to create a melt (no longer necessary). The visible stinginess was not guilty of buti.
The final touch is to blow through (with just a gum pear) the lenses of the laser mechanism (it is not possible to wipe them every time) and the drive goes back.
Failure of the DVD or CD drive in laptops is the most common problem in devices that have been used for more than 2-3 years. Pil, who definitely settled on the line that focuses, after many fatal exploitations, singly, if you don’t bring the drive to full operation, then make your robot less reliable and reliable. The reason for the continued difficulty of recording or recording information from the computer to the optical device may be either a hardware or software malfunction of the system. Please note: the optical disc drive on laptops may be unable to read information from DVD discs for a variety of reasons.
First of all, it is necessary to 100% disable the possibility of a software failure in the operating system. You can simply insert a disk into the drive, which you can vikorystuvat as a vantage one. Use either an installation distribution with Windows or any service disk for working with a hard drive, as well as for cleaning up viruses, banners, preparing the system before installing the operating system from scratch, etc. Heads up - put in the BIOS that the DVD drive is the first thing you want. It is from this, and not from the hard drive, that you need to work hard. Of course, anyone who independently installed the operating system either from a disk or from a flash drive knows what to do. If the installation of such a disk will be entirely successful, then there is a problem with the installation of the operating system, as well as with drivers, as well as with software products that can, in one way or another, change the system configuration Both virtual and physical optical drives. Uninstall all dubious software for burning and copying DVDs, and also check in the device manager so that your drive is correctly identified. Of course, it is practically impossible to describe all software problems within the framework of one article, but it is possible to give universal pleasure: to update the system.
Otherwise, if the disk drive is trying to catch the old disk, then, after all, there may be a hardware problem. Most often, the most common problem comes down to the need to clean the lens that focuses. Saw, spending on this lens, skips the menu of the laser head to normally transmit the signal from the DVD disc. If at any stage of operation this leads to problems with reading or writing, then one “fine” day the drive may simply be able to read a completely clean and new disk. The best way to avoid this problem is with a clean focusing lens.
The contagion of great expansion has caused the so-called disks to be cleaned. The idea behind such discs is incredibly good, but technical innovation will never be more pleasant. These images can, instead of the cortex, simply “finish off” the sensitive mechanisms and optics of the laser head. Also, incorrectly removing disks that need to be cleaned can lead to the fact that the user himself simply “adds” the disk drive. The instructions for such disks are often written in either English or Chinese, in order to understand the principle of operation, the use of such a disk is simply inaccessible to Russian people. The head of the koristuvachs lies in the incorrectly applied liquid to be cleaned. As usual, you need to apply it only on small small humps, even as little as possible, spreading the disk at approximately 45 degrees to the horizon line. The sheer volume of this product simply floods the laser head, making it virtually impossible to read information.
If we talk about Chinese wheels in the 100-150 ruble category, then their purchase will not be justified both from a practical and economical point of view. And if your problem is not in the lens, then it’s all pennies down the drain. In order to protect the reputation of discs that need to be cleaned, it is significant that new contactless discs that need to be cleaned have now begun to appear. Their main advantage lies in the fact that they work like wind turbines to blow through the laser head without direct contact. We recommend that you wash the discs that need to be cleaned without damaging the sensitive elements of the optical drive.
How to clean a DVD drive without a disc, what to clean
There are plenty of repairmen who would like to recommend that you use disks to clean them rather than use them at all. A clean disk is a treasure for the beginning and a gift for the home. You can clean the drive more professionally and accurately once you remove it from your laptop and take it apart. To disassemble the drive, there is no need for any kind of folding equipment or brains. All you need is a table, a set of screws, a violin, a head, a syringe, ear sticks, and also isopropyl alcohol.
How to remove the drive
First of all, you need to unlock your laptop. Turn it face down and remove the battery.
In fact, there is a fact: on all modern laptops, all the fastenings of the disk drive to the laptop are installed with just one screw. We take a thin cross twist and twist it.
This method can also be used as a backup method if you need to remove the disk completely, turn on the electrics, and deplete the battery. After the disc drive is pulled into the technological opening of the head or the clip, the drive will open, and you can retract it completely by pulling the disc tray.
How to remove the drive
By turning the open optical drive with the front side down, you can mark the back panel cover, which houses many important elements of the laser system.
You take out 4 guints, rub them together, and the lid will move without the least bit of fuss on your side. After removing the cover of the rear panel of the laser drive, we gain access to the back of the laser diode, as well as the optical system.
Then you can put on the cover and also tighten the 4 fastening screws.
How to clean the lens that focuses
The lens is very sensitive to touches, so it’s best not to scratch it with your hands or tools. For starters, you can try blowing from a spray can under tight air.
If this does not help, we recommend that you use a vicor ear stick, first soaked in 90% isopropyl alcohol, to wipe the lens. Use another dry, clean end of the stick to remove excess alcohol. Remember that it is simply unacceptable to vikorize someone’s cologne, moonshine, or bottle of wine. You're just going to do some mischief. Isopropyl alcohol easily evaporates, is absolutely non-toxic, and also does not leave traces on the lenses, which is very important within the scope of the technical specifications. Then you need to dry it again from the can with tight air. All you have to do is take everything out, insert the drive and tighten the screw. The folding is simple and intuitive.
Of course, it is important that in such situations, a breakdown will still not be possible, since it can happen in a LED laser that burns out, in a mechanism that has worn out, in burnt-out driver microcircuits, etc. The remaining repair option is to completely replace the DVD drive.
This article is about how to carefully reassemble and reassemble the mechanisms and parts of an old or “dead” CD/DVD drive. What makes the folding device so good is that its parts can be reused in different types of self-propelled machine lovers.
An unnecessary CD or DVD drive can be pulled from your old computer, but if there is no such thing, then you can go to the nearest computer repair shop - they will only do so for the sake of getting rid of unnecessary “junk” for them, rather than deal with recycling I mean.
The first thing you need to do is to unscrew the screws and remove the cap.
It is important that the red arrow in the photo is marked 1, you need to push it to the right until it stops and push out the disc tray (photo 2). Press in the fasteners located on the sides of the case (in the photo there are 3 marked with red circles) and remove the front panel of the drive. The housing can be removed from the drive.
We remove the electronic board, for which you need to insert a plastic clamp, indicated in the photo with a red arrow. Then remove the darts that came out of the roses. We will pay the fee until the last hour - it may come in handy for something.
Below in the photographs you can see how the motor of the disc tray mechanism is removed. Everything here is just stuck. It was impossible to dismantle the wooden board and remove the following parts for your creativity:
- green LED,
- stationary electric motor 6 volts,
- Two electrical buttons.
We disassemble the disk tray mechanism and remove two gears; they can be used for making a small gearbox.
The laser positioning mechanism is removed from the plastic housing. This is the most valuable element of a CD/DVD drive, and can be used in the production of a mini-CNC engraver, plotter, laser engraver or 3D printer. The chassis is held in the body by two screws on one side and two plastic pins on the other (amazing photo below), so removing it is not difficult.
The motor is used to wrap a CD or DVD disc, for which you have to turn two screws. This electric motor is brushless, so don’t worry that it requires an electronic speed controller when simply connected to the power supply.
After minor reworking, some modellers are using electric motors in their aircraft (report: http://www.flyelectric.ukgateway.net/cdrom.htm#top).
We unscrew the motor from the worm, first removing the block of laser diodes.
DVD drives have bipolar motors; to drive them, drivers on special microcircuits are used, for example: L239D.
Blood motors are important for precise positioning of various devices and are widely used in automation and robotics.
The bloody motor of a CD/DVD drive can be stuck, for example, in a small CNC engraver.
Let's start disassembling the laser diode unit. All CD/DVD writeable drives have two laser diodes, one for reading and the other for writing (burning) discs.
