Lesson overview:Optical and magnetic storage

  • In this lesson, we will build on what we learnt in the previous 'Secondary Storage' lesson; this lesson involves exploring optical and magnetic storage devices. We will learn how each type of storage operates, and explain how data is written and read from each device. We will then actively rank the storage device in a number of key areas of comparison.
