Splitting, collection and selection are just simple cuts from the original version.
Original version and D version. In order to control the cost, version D generally doesn't use the best polycarbonate.
In the production process, the injection molding cycle of optical discs is usually 3 ~ 5 seconds, while version D will speed up the operation of the machine and make the injection molding machine work in a short molding cycle, which will inevitably lead to the phenomenon that some optical discs are dissatisfied with the information pit.
In terms of aluminum plating parameters in the vacuum sputtering process, Manufacturers who pay attention to product quality will control the aluminum layer to a sufficient thickness according to the reflectivity requirements. D-version manufacturers will plate the aluminum layer as thin as possible to save aluminum targets and time. Therefore, when some D-version discs are facing the light, they will find that the aluminum coating is uneven and can see through, and the reading performance of such discs is relatively poor, and the bit error rate increases. < P > Generally, 1kg of UV glue can coat 6 ~ 7 discs in regular factories. However, 1kg of UV glue from some D-plate manufacturers' factories can coat discs much larger than this amount. This certainly saves the cost, but at the same time, the glue coating of discs is not up to standard.
On-line inspection is mainly for the initial inspection of discs.

If the quality of the discs is not up to standard, Then the machine will automatically sort unqualified CDs, and if it is a D version manufacturer, it will close this process to save time. Moreover, genuine manufacturers will also conduct a manual inspection of the CDs coming off the line according to their own quality inspection procedures to ensure the quality of the CDs entering the next process ...

For the works that they can't put it down, they have to go back and buy expensive originals, which may be the sadness of domestic music lovers.
For some pop songs with strong timeliness, D version has a high cost performance ratio. As a collection,
