Explanation:
Detailed explanation-1: -R discs use a dye-based layer (organic dye) for recording data. These are “write-once” discs and cannot be erased by CD or DVD drives. The organic dye used in the data layer of R discs degrades naturally but slowly over time.
Detailed explanation-2: -Preservation and storage. CDs and DVDs are not suitable for long term archival use. Data is stored on Optical disks in the form of marks or pits that either absorb or reflect the light from a laser beam. The disks have a plastic and metal layered construction that makes them susceptible to damage.
