光盘由聚合塑料层、铝膜层和保护层三部分组成。它的性能虽然稳定,但许多使用者由子对光盘特性不了解,以致保护不当,使光盘遭到损坏。 误区一:保护好塑料面,光盘就没问题。 许多人都知道光盘在使用中激光束是从塑料面射入的,塑料面上的划伤、指印和灰尘会影响数据的读取,但塑料面的划伤通常可以通过误码纠正来补偿。相比之下,保护涂层
Disc consists of polymeric plastic layer, aluminum layer and protective layer composed of three parts. Although its performance is stable, but many users do not understand the characteristics of sub-CD, resulting in improper protection, so that the CD-ROM was damaged. Misunderstanding one: protect the plastic surface, no problem on the CD. Many people know that when a disc is in use, the laser beam is incident on the plastic surface. Scratches, fingerprints and dust on the plastic surface can affect the reading of the data. However, scratches on the plastic surface can usually be compensated for by error correction. In contrast, protective coatings
