FAQ
Frequently Asked Questions
No, not all. Older CD players and some early computer CD-ROM drives may not be compatible with the specific reflectivity and formatting of CD-RW discs.
Typically, a CD-RW can be rewritten approximately 1,000 times, though this varies by manufacturer and usage.
No. They are different formats with different storage capacities (CD-RW ~700MB, DVD-RW ~4.7GB) and require different drives to write and read.
Because flash storage (USB drives, memory cards) and cloud storage are faster, more convenient, and offer greater capacity, making rewritable optical discs largely obsolete for everyday use.
