1. Why is it important to convert analog information to digital form and vice versa?
2. Briefly, list the process required to fabricate an IC circuit (hint: recall the video by Global Foundries we watched in class):
3. What is the main difference between longitudinal and perpendicular magnetic recording? Which one is currently implemented in HDDs? (hint: a link to a video explaining this can be found in the lecture slides)
4. What are the components of a hard disk drive (hint: recall the videos on HDDs watched in class)?
5. Which HDD technology has the potential to store more data density? SMR or HAMR.
