Previous Year Question (PYQs)



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





Solution

Seek latency is the time taken by the disk arm to move the read/write head to the required track.

The arm does not move with uniform speed throughout the seek operation.

It takes time to start moving and also takes time to stop at the required track due to inertia.

Because of this starting and stopping inertia, seek latency is not linearly proportional to the seek distance.
