Identification of genuine and fake CDs:

First, is the painting regular?

Often high-quality burning discs are absolutely exquisite in both internal performance and external workmanship; Fake and shoddy products will not only cut corners, but also make rough work. As far as painting is concerned, poor quality optical discs ignore the protection rules of surface painting, even the circular painting rules, but ignore the coating and aperture. Especially in terms of painting rules, some inferior burning plates actually have paint overflow, and even the inner ring and outer ring of the plates have different coating colors. In fact, these phenomena are poor performance of rough workmanship, so don't consider these discs.

Second, whether there is leakage.

Discs with leakage have great data security risks, so this method can quickly distinguish whether they are safe or not. The method is to carefully check whether the surface of the burned CD is coated with paint. If it is found that some parts of the burned disc are not protected by paint, there will obviously be leakage in this place. Even if we use this burned CD to save data, we may not be able to access this leaked CD with an optical drive in the future, so using a leaked burned CD will bring instability and future CD access.

Third, is the aperture clear?

Because the surface of genuine burned CD is coated with pigment to protect data, this coloring is regular, specifically, it is coated on the surface of burned CD in the form of pores according to a certain level. Generally speaking, the more layers are painted, the higher the security of data protection, the clearer the aperture is painted, and the higher the stability of data recording and data access. Therefore, the way to check whether the aperture is clear is to point the back of the burned CD at the light, and then carefully check the coating on the surface of the CD. If there are many layers and the aperture is clear, it means that the burned CD is of high quality. If the coating is less and the aperture is unclear, it means that the quality of the burned CD is not too hard. If the coating is not clear at all and the aperture is not clear, we can conclude that the burned CD must be a fake and shoddy product.

Fourth, whether the touch surface is flat or not.

As we all know, if the surface of the burned CD is uneven, the CD will shake or shake due to the unstable center of gravity during high-speed rotation, and in severe cases, the CD will jump, so that the surface is easily scratched by the laser head, which not only leads to the loss of important data, but also damages its optical drive/recorder. So when we check the quality of the CD, we must carefully observe whether the surface of the CD is flat or not. The most effective way is to touch the outermost edge of the burned CD by hand to see if there is any uneven feeling. It is best not to use burned discs that can obviously feel the unevenness on the surface of the disc.

Verb (abbreviation of verb) Is protective paint formal?

At present, in the market of burning optical discs, regular burning optical discs all have a label layer, and the label layer is generally covered with data protection paint. Of course, the coating of this protective paint is also very regular. However, the label layer design and protection of many inferior discs are obviously not in place. They are either not painted with data protection paint, or only painted with a little protection paint, and even have traces of multiple printing. Obviously, when using these discs to protect data, security and stability will not be guaranteed. Even if these CDs can be burned and accessed normally in a short time, they will be easily worn with the extension of use time, so there is no protective paint on those labels.
