Explanation:
Detailed explanation-1: -Currently, CD-RW discs can be rewritten approximately 1000 times. What is the shelf life of unrecorded CD-R and CD-RW discs? The unrecorded shelf life of a CD-R or CD-RW disc is conservatively estimated to be between 5 and 10 years.
Detailed explanation-2: -Heated to one temperature, the material cools to a transparent state; heated to another temperature, it cools to a cloudy state. By changing the power (and therefore the temperature) of the writing laser, the data on the CD can be changed, or “rewritten."
