📝 Sample Questions

Q1. What term describes the method where the rotation speed of a disk varies to keep the linear data rate constant as the head moves toward inner tracks?

🔹 A. Constant Angular Velocity (CAV)

🔹 B. Constant Linear Velocity (CLV)

🔹 C. Zoned Bit Recording (ZBR)

🔹 D. Fixed Sector Mapping

💡 Difficulty: easy | ✅ Correct: C

Q2. Why do tracks in the outermost zone of a disk typically hold more sectors than tracks in the innermost zone?

🔹 A. Because outer tracks have a larger circumference, allowing more data to be placed at the same linear density

🔹 B. Because outer tracks rotate faster than inner tracks

🔹 C. Because outer tracks use a different encoding scheme

🔹 D. Because outer tracks are less prone to defects

💡 Difficulty: medium | ✅ Correct: A

Q3. How does zone bit recording improve storage efficiency compared to using a uniform sector count per track?

🔹 A. It matches sector density to track length, allowing outer tracks to hold more sectors and inner tracks fewer, reducing wasted space

🔹 B. It forces all tracks to have the same number of sectors, simplifying the controller design

🔹 C. It eliminates the need for error correction by using larger sectors

🔹 D. It reduces the number of cylinders needed for a given capacity

💡 Difficulty: hard | ✅ Correct: A
