When it comes to DVD, many friends may no longer pay attention.Indeed, the popularity of the Internet and the popularity of mobile phones have made the monotonous playback function of DVD become ribs.However, for feelings, having a brand new and beautiful DVD player is far more surprising than getting new mobile phones.The DVD player is now more suitable for listening to music, because the music it played is better than headphones in sound quality and sound.In addition, the rise of convenient DVD players, many young people who are pursuing novelty are also willing to use it as a carrier to play music.Therefore, the DVD player seems to be declining, but it is still quietly developing in the young people.Today, lets take a look at what to do if the DVD optical drive does not read the disk and how to buy the DVD optical drive.
What should I do if the DVD optical drive does not read the disk
The optical drive is the most aging component in the current computer, and most of the laptop computer optical drives are no exception.The optical drives of the laptop are mostly dedicated products. After damage, there may not be the same type of spare parts replacement.The replacement is labor -intensive and time -consuming.The main causes of light drives cannot read discs or damage include problems such as bald head, bald bias, bad synchronous motor, and south bridge chip.
1. Optical drive laser head is aging
Unable to read the data can increase the output power of the laser head. There is a regulating screw behind the laser header seat. Slowly rotate about 15 degrees. If it does not work, turn 15 degrees, and repeatedly test until you can read the film.
Second, the virus light drive in the computer
In the registry, it was maliciously blocked in the "My Electric HKEY_CURRENTUSER/SOFTWARE/Microsoft/Windows/Currentvrsion/POLIITES/XPlorrs binary value.Change this value to "00 00 00" (01 00 00 00 is A, 04 00 00 00 C, FF FF FF FF is hidden all the drivers).The disk is lost, and some viruses do not lose the light drive letter, but the optical drive read the disk. What kind of discs cannot be read, but it can be started with a CD -ROM.
Third, the laser head accumulates too much dust
If you will operate as follows, remove the light drive, open it, use the cotton ball to dip the water -free alcohol or distilled water to wipe the laser head a few times (wipe parallel, do not wipe the circle. Do not use a cleaner -it will form a layer of membrane), dryTwenty minutes, install it again.You can work for you for a while.Ordinary users do not have the ability to do it. It may be difficult to recover when disassembling and cleaning. It is recommended to buy a CD -ROM CD -ROM to buy it. Generally, there are places to sell discs.
What should I do if the DVD optical drive cant come out
Tools/raw materials
Optical drive, toothpick
Method step
1. There is a compulsory outlet hole on the optical drive panel. Generally, it is very useful when the optical drive fails to get out of the warehouse.We also need to prepare a hard object such as a toothpick or a closer needle.
2. Use the toothpick to insert the emergency outlets. At this time, a small part of the light drive tray will pop up.
3. At this time, just pull out the pop -up tray out.
4. Lets take a look at the internal structure.The so -called forced outlet is to push the tray with the help of external forces.
5. In the internal structure, we will see that the pop -up of the tray needs to be driven with gears and belts.Most optical drives cannot be out of the position because there are problems with these two places.
6. Followed by the fault, we can choose to replace the wear gears or aging belts.Applying for compulsory warehouses can only be cured and not cure, and replacement parts can only be cured.However, the general optical drive will be aging, and it will not take long for it. If it is seriously aging, it is best to consider replacing the new optical drive.
Precautions
① The toothpick must be smaller than the outlet.
② The belt that is changed should not be too tight and overly loose.
How to buy DVD optical drive
Most buyers are the first to consider, and they are also a question of asking merchants before buying.But what is the whole district, maybe it is just a term in the hearts of many consumers.I thought it would not be good without the whole district.In order to enable readers to understand more, first of all, briefly introduce the concept of district code.The location code is defined when the DVD is initially formulated, and it contains the limitation of the zone code.Both the DVD movie disc and the DVD playback software in the home theater must have a built -in area code limited.
The DVD industry divides the world into six districts:
Area 1: United States, Canada
Area 2: Japan, Europe, South Africa, the Middle East (including Egypt)
Area 3: Southeast Asia, East Asia (including Hong Kong)
District 4: Australia, New Zealand, Pacific Island, Central United States, Central United States, Mexico, South America, and Caribbean Sea
Area 5: Eastern Europe (former Soviet Union), India, Africa, North Korea, Mongolia
Area 8: Special international area (aircraft, ships, etc.)
When the movie is made into a DVD, the distribution scope of DVD will be separated according to the zone code. If the user purchases DVDROM only supports six districts, it is impossible to play discSeveral dishes with location code can be read and recognized.This is the improvement of chips based on Chinas domestic situation and in order to increase their competitiveness.In fact, most of the DVD discs sold in the market are in the six districts, but there are also a few smuggling or pirated versions of the first or second district. At this time, the DVD in the district is used.Most of the DVDROMs sold in the market now are "the whole district". No matter which dealer says that the products they sell are the entire district, it is difficult to find the whole district!Is this really the case?The editor learned that only the two large multimedia companies, two multimedia companies, acknowledged that their DVD was locked, and their price was expensive, so it was not recommended to netizens.In addition, there are a lot of merchants who sell low -speed DVDs also call their products in the entire district, but in fact, a random attachment of a software is used to change the bit code, and the number of changes is limited. At that timeI cant change it again.Therefore, when buying, bring a large number of DVD discs with various regional codes to try one by one, but the owner of the optical drive is hard to say, so it is recommended to say in domestic brands with good after -sales service and quality.Selection is more direct.
