Answer 1

"The key difference between optical storage media, such as DVDs and CDs, and magnetic storage media, such as hard drives and traditional floppy disks, is in how computers read and write information to them.

Optical storage media uses light; the magnetic storage media uses electromagnetism.

Computers are binary, meaning that for them to fetch information, it has to be raged down to a series of digits, each of which is a 0 or a 1. Storage media use different techniques of representing those digits.
