Since the successful development of optical disk storage technology as a replacement for tape drives in the early 1970s, CD and DVD-based platters have replaced cassettes and video tapes in just 20 years, becoming a new carrier for music and movies. The optical disc storage technology has repeatedly boasted of its advantages when it entered commercial use in the 1980s. Digital technology and long-term storage time have become the reason for the rapid popularity of optical disc storage technology. "In the memory of ordinary consumers, CDs and DVDs of optical media can be used as a once-and-for-all collection. But after more than 20 years of testing, the once-and-for-all collection has become a bubble," Thomas Fryer said. So, what is the life of the disc?
The life of a disc depends on three factors:
1. Physical and chemical properties of the optical disc itself. The optical disc is composed of a polymerized plastic (polycarbonate) layer, an aluminum film layer and a protective coating. If the ambient temperature is too high or too low, the plastic will age and the aluminum film will be slowly oxidized by contact with air. In addition, the data of the CD can only be read, can not be rewritten, can not be repaired or identified after the damage, can only be discarded, and is very different from the disk.
2, daily maintenance. Discs are highly used in multimedia applications, and improper use and improper maintenance methods can shorten the life of the disc. The CD case, CD cleaning brush, CD cleaning machine and CD-ROM cleaning disk bring great convenience to our use and maintenance of the CD.
3, the update of computer technology, the faster and faster the optical drive, the "eyesight" is getting worse and worse, many of the original can read the disk can not read now.
    The above is the deciding factor about the life of the disc, I hope to help everyone.
