Scratches on discs have a negative effect on their functionality and how well they maintain data. Repairing Scratched Discs Knowledge of what caused the scratches, where it scratched at (and how), are key to knowing if the damage is something that can be repaired.disc repair (ad)
For example scratches on the reflective side of a disc goes to show that the data is probably at risk. If the disc, in this case, happens to be beyond repair, well, I am afraid the precious data is all gone. This is because any incurring damage on the top layer will directly affect the reflective layer (the one necessary to read the data).
If a disc has scratches on the bottom plasic layer, then it is another situation altogether. Most of these scratches are easily repaired by using some resurfacing and polishing methods. Resurfacing: The process of removing a thin layer from the surface of the disc in order to erase imperfections and make it readable again. There are several commercial products and services available that specialize in this type of repair, which now make it possible for users to recover their discs.
Improvements in Scratch Resistance
Advances in disc manufacturing have since made it possible to create scratch-resistant discs. In addition, manufacturers are now using customized coatings and materials to further increase the life of these products. For example, TDK Durabis technology has created a strong polymer coating that is resistant to scratching but also does not lose clarity when damage occurs for disc reading. These innovations were created to decrease the methods of scratching and stretch out the life span of optical media.
To sum it up, a disc cannot be fixed if scratched down below the reading surface (the part that touches the laser), but can other wise be restored back to working function. Moreover, ongoing improvements in technology are bringing about durable discs with the ability to simply stand up to repeated use.
