Is a CD a magnetic storage device?

Answer 1

Sure, but it's kind of a pain. A benefit to a CD-rw is that it can be written or re-written whenever you want, so if you were storing documents on it, for example, later you could re-burn updated versions of those documents to it. The downside is that anyone could come along and write over your data. Also, a CD, once it is burned, is usually taken out of your optical drive tray and put away somewhere. While it's outside the computer it is vulnerable and can be scratched. If you're using a hard drive or solid state drive for memory, they are better protected.

Also, I thought of another possible piece of information you might be asking. I notice you asked if the drive itself can be used as storage. On some computers, there is an option to remove the optical drive (the drive that burns and reads CDs, DVDs, etc.) and replace it with a storage drive instead.

Answer 2

No, it is an optical storage device. A laser is used to etch the data into a dye layer. The drive reads it with another laser, which is scattered differently by marked and unmarked parts, which the computer interprets as 1's and 0's.

Answer 3

no, it is an optical storage device made by a laser burning different size and shape ridges, then read by your CD player.
