Question 1

What is the meaning of constant angular velocity in hard disks?

  • The disks rotate at varying speeds.
  • The disks rotate at the same speed throughout.
  • It determines data integrity.

💡 Hint: Think about how this might simplify data retrieval.

Question 2

True or False: Seek time is the time needed to move the head to the correct track.

  • True
  • False

💡 Hint: Recall the importance of positioning for efficient data access.

Question 1

Design a simple simulation model for a hard disk controller that demonstrates data retrieval from different tracks and the effect of seek time and rotational delay on efficiency.

💡 Hint: Consider the components of seek time and rotational delay during simulation.

Question 2

Explain how varying the bit density across tracks affects the overall storage efficiency of a hard disk. Provide a calculated example using arbitrary values.

💡 Hint: Calculate based on different storage needs for inner and outer tracks.
