Question $2$

Suppose that records are stored on a disk with the following characteristics:

Average Access Motion Time $0\mathrm{.}033$ sec

Disk Rotation Speed $7200$ rev. per minute

Data Transfer Rate $307\mathrm{.}200$ bytes per sec

Assume one record in one block

$($b$)$ If $20$ records are stored on a track.

$($iii$)$ What would be the data transfer time for $82$ records stored sequentially on tracks in different cylinders and each track has fixed read$/"$Tite heads?
