DVD disc repair and repair of other optical discs are required when these media have degraded or have been damaged. Optical media are not indestructible and this is why proper storage of the media and proper handling are required. These ensure that the media and your valuable digital scrapbooking projects and other digital information such as videos and photographs are not lost.
Perhaps the principal way that optical discs can be damaged is because of physical damage caused by poor handling. Poor handling of optical media can lead to CD scratches or DVD scratches and CD and DVD scratch repair methods will be required, the delamination of disc layers, disc warping, disc cracking, disc breakage, and contamination of disc surfaces with fingerprints, dust, or other debris.
For CDs and DVDs affected by these problems, DVD disc repair or disc repair for CDs and other types of optical discs would be required to make the discs playable or readable. To address the problem of surface debris and fingerprints on CDs and DVDs, cleaning compact discs and cleaning DVDs are required.
Another source of damage to optical media can be caused by the storage enclosure. For CDs and DVDs, the best storage enclosure is a regular size jewel case. Jewel cases can also be purchased that are made of polypropylene instead of polystyrene. The polypropylene jewel cases are more rigid and will not shatter like the standard jewel cases. Storage enclosures such as thin jewel cases or sleeves made of paper or plastic are not recommended and can lead to physical or chemical damage of the disc. DVD disc repair or other disc repair may be required if optical discs are stored in enclosures that are not recommended.
The placement of adhesive labels on the top of CDs and DVDs is a common way that these media are damaged. If a CD or a DVD has an adhesive label on it, either in the short term or in the long term the disc will be negatively affected. DVD or CD repair likely requires the removal of the label in order for the media to function properly. Label removal must be performed carefully; otherwise the disc will be irreversibly damaged.
The storage environment can promote the degradation of optical media. A storage environment that is high in pollutants can lead to disc rot or corrosion of the metal layer in CDs, DVDs, and other optical disc formats. Elevated temperature, elevated relative humidity, and light exposure can all lead to deteriorated optical discs. Recordable CDs and DVDs use dyes to store the digital information. Some of the dyes used are less stable and will degrade fairly quickly under elevated temperature and relative humidity or too much light exposure. Erasable materials use a different technology to store information, but these can also be negatively affected by the above mentioned factors. When degradation of the recording material occurs, DVD disc repair or any other optical disc repair likely cannot restore the disc to the point where the information can be retrieved.
In addition to the above stated problems, CDs, DVDs, and Blu-ray discs may not play properly simply because of player or drive problems and player or drive repair is required. The equipment may also damage the optical media as discussed at the circular scratches page.
