1. What is the angular speed of a disk drive?

2. What are the three time components of a disk drive operation?

3. Which time delay is due to the inherent slowness of the stepper motor?

4. Which time delay is often the longest?

5. Where is the bit density the greatest? Circle one:

     near the center               near the outer edge

6. If rotating the platters faster increases the data transfer rate of a disk drive, why not speed up the main motor?
