Review Questions
Data transfer rates
  1. What is the angular speed of a disk drive?
answer...
its rate of rotation, such as what rpm it is spinning at
  1. What are the three time components of a disk drive operation?
answer...
  1. seek time
  2. rotational delay
  3. data transfer time
  1. Which time delay is due to the inherent slowness of the stepper motor?
answer...
seek time
  1. Which time delay is often the longest?
answer...
seek time
  1. Where is the bit density the greatest? Circle one: 
     near the center               near the outer edge
answer...
near the center
  1. If rotating the platters faster increases the data transfer rate of a disk drive, why not speed up the main motor?
answer...
because the bearings will wear out sooner and it takes more energy to spin the platters ever faster
