For a magnetic disk with concentric circular tracks, the seek latency is not linearly proportional to the seek distance due to

1. non-uniform distribution of requests
2. arm starting and stopping inertia
3. higher capacity of tracks on the periphery of the platter
4. use of unfair arm scheduling policies

Correct Option: C

The seek latency is not linearly proportional to seek distance due to the higher capacity of tracks on the periphery of the latter. The higher capacity of the tracks is responsible for the presence of this certain amount of time is required for this cells to reach the read-write head so that data transfer can take place.
