Part a)

You have studied in this course that Tracks are the circular division of the disk and the Sectors are the longitudinal division of the disk. A typical track is shown in yellow; a typical sector is shown in blue. A sector contains a fixed number of bytes -- for example, 256 or 512.
As per division like above, there is a clear difference in size of sectors on inner and outer tracks which causes under utilization of the larger, outer tracks of the disk. What mechanism is used to improve disk surface area utilization?
