What is the difference magnetic storage device and an optical storage device?
optical storage writes and retrieves data using a laser or similar. Magnetic storage uses a coating on a disc or tape to hold data, by manuplating the tiny ferrous elements on the surface it can store information. A CD is optical storage. It has a series of lands and pits (ups and downs) - as the laser passes over these it converts them into 1s and 0s.
