Lesson 6 Optical and magnetic storage
This lesson builds on from the first secondary storage lesson; it involves exploring optical and magnetic storage devices. Learners will need to be aware of how each type of storage operates, and to explain how data is written and read from each device. The last activity has them synthesising the characteristics of the storage mediums to compare them. Using a combination of their learning, and a reference table, learners will actively rank the mediums in each of the key areas of comparison.
Learning objectives
- Explain how optical and magnetic memory stores data in the form of binary
- Describe how data is read from and written to optical and magnetic memory
- Apply knowledge of storage devices to compare the three mediums of storage
